Q: "No Audio Output Device is installed"

HELP!!! My sony vaio laptop no longer has sound. I have tried uninstalling and reinstalling Realtek, I have restored my whole computer, but during the boot up, Realtek does not get installed, it comes up as an error 505. My USB ports are also not working, and I need them to be working really soon. I have done troubleshooting and all sorts of other tests to figure out the problem, but nothing is coming up. Any suggestions help.

Preferred Solution: "No Audio Output Device is installed"

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I'm running a Dell XPS 420, which came with Windows Vista. I decided this morning that I was going to give Windows 7 a try, backed up some media on another PC, and did a completely fresh install.

Everything worked perfectly, I didn't even have to install any drivers. My native resolution was automatically correct, the sound worked, the internet worked, everything was dandy. It worked perfectly, and for the record, I really enjoyed it. I used it for several hours, getting used to the new features and whatnot.

I went to sleep for a few hours, and then went out for a while. When I came back, the sound had stopped working. It gave me no error at the time, it just didn't work. WinAmp wouldn't play my MP3s, Youtube videos were without audio, system sounds weren't playing, and yet, the volume was enabled and at an audible level of 67. My speakers were still connected properly, too.

I figured maybe a reboot was in order, and when I restarted, there was no sound still. Now, however, the speaker taskbar icon had a red x next to it, with the words "No Audio Output Device is installed." on the tooltip. I rebooted again and there was no change.

Using the Windows 7 trouble shooter, it says that "Hardware changes might not have been detected."

The odd thing is, this has happened to me before with Windows Vista. I wanted to perform a clean re-install of Vista, and when I did so, the sound worked perfectly for a few hours, before going out again. I would re-install Vi... Read more

A:Audio stops working, "No Audio Output Device Installed"

Hi filmtrauma, welcome to the forums.

While you have been asleep, Windows Update may have installed a new Sound driver for you which may have caused this error. Open Windows Update and click 'View Update History'....

You could try downloading the latest drivers from the hardware manufacturer, a lot are now supporting Windows 7 too..

Also, is your sound hardware plugged in (to the motherboard) securely? It's rare but i've dealt with some cases of hardware coming loose, might be worth a look. Another thing to check may be the temperature of the card, it may be getting overly hot due to a dust build up (might not be, i'm not 100% up-to-date on all sound hardware).

Hope this helps

I don't know if any of this is related, but I wanted to provide as much information as I could for you gurus to deal with. So here's what happened:

I left my ASUS K55A laptop in sleep mode. I opened the lid to wake it up, logged in, and then everything started to load really slowly. This hasn't happened before, and the computer quickly BSOD'd in that new Windows 8.1 fashion. It restarted and scanned/repaired my D drive, again in a very slow manner. It took maybe 20 minutes just to get to the login screen (as opposed to maybe a minute). I login, and again, everything's very slow. This time, I just hit the power button and reset the laptop that way, hoping it'd fix things. Unfortunately, the same thing happens. After doing this about 2 or 3 more times, each time spending about 20 to 30 minutes, I just let it run after I log in. I manage to click the "Restart" option on the side after waiting eons for it to respond to my clicks. I get it to load and it booted up normally.

Or so I thought.

My D drive was suddenly inaccessible and my little volume speaker at the bottom right had the red X beside it, saying "No Audio Output Device is Installed". I spend another billion years trying to fix my D drive, changing permissions and allowing full control, and eventually getting full access again, most likely with some unknown ramifications. I found out after that although my C drive didn't suffer from the same problem as my D drive, the C drive would keep asking me f... Read more

A:Asus Laptop/RealTek "No Audio Output Device is Installed"

From your description, I'm going to suggest what I try to avoid at all costs. Do a complete reinstall. I know its a hassle but sometimes its what is needed.

Backup your user data to some external media (USB flash drive, CD/DVD media, etc) first as the reinstall will wipe it all out. Then do the reinstall, using the recovery mode that I assume ASUS has (most PC vendors have a recovery partition on the hard drive that will allow restoring to the original factory condition).

Warning, I am NOT a computer person at all, but have spoken to some and tried several repairs. I have a Sony VAIO VPCEA24FM laptop, running windows 7 64-bit and the sound has randomly stopped working (made no changes to anything that I know of). There is a red circle with an x in it on the volume icon on the taskbar, and when I hover over it it says "No Audio Output Device is Installed." However, when I open the device manager and click under sound controllers, Intel (R) Display Audio is listed and if I click on it, it says this device is working properly.

I tried to update the drivers and it says I have the most up to date. When I open sound on the control panel it says no audio device is installed and even when I right click and click "show disabled devices" nothing is shown. I have tried microsoftfixit, and it doesn't help. I have also tried to download the Realtek High Definition Audio Driver from the Sony website, and it downloads and installs and then a window comes up that says it may not have installed properly, and asks, "reinstall with recommended settings?" i click ok and it gives me a message that says, "This update can only run on Microsoft Windows Vista, Microsoft Windows 7" and all there is is an "ok" button, which i click, and it does not reinstall. HELP I'M AT MY WIT'S END!

A:Sony VAIO laptop "No Audio Output Device Installed"

Hello and welcome Samark had a look at the Sony site and you might try this for the audio driver, as I prefer to go to manufacturers sites rather than the Device Manager which I personally don't find all that reliable.


there is also this but try the Sony site first http://www.realtek.com.tw/

As a matter of curiosity you haven't dropped the laptop or spilt anything on it by any chance?

Hello All,

I am sorry if this has been addressed but I have been looking everywhere and have tried so many things to resolve this issue to no avail.

My Sony laptop VGN-FZ21Z VISTA home premium 32 bit has a little red x next to the audio on the bottom right toolbar. No Audio output device is installed is displayed when I hover over it. I have gone into the device driver to check the problem and no audio device is installed. I have tried to download the driver from the Sony UK website and it says object not found restart computer and try again. There is then a prompt to install with the correct settings and it tries again and says I have the wrong device. I have also reset my computer to factory settings and still that little red x is there. I have looked everywhere for the correct device driver but can't seem to find one for this model.

Thank you kindly for your time.

Recently when I was trying to enable my sound card so I could make YouTube videos, I managed to somehow break my sound. I have a windows 7 64bit computer that runs realtek hd audio and nvidia hd audio. I have tried reinstalling windows and that does not work, as it comes up with an error message "upgrade failed, restart and then select updates when prompted" no mater how many times I do this It does not work. Please help!

A:Sound error "no audio output device is installed"

Reinstalling Windows probably is not the answer. The sound device (RealTek) is apparently the problem.

Without knowing what you did to "enable my sound card" we can't really say what is needed to make it work again.
Filling out the My System Specs will also help someone to try and help you.

What is the status of the RealTek in the Device Manager? Is it listed and does it show an error code or working OK?

first i want to comment that that error has strange capitalization issues...


i am running vista home premium 64 on an hp pavillion dv2845se verve entertainment notebook pc and i have the dreaded no audio output BS

when it first started happening, it would come and go as i restarted or hibernated. now its mostly full on sucking.

i have updated drivers, restored to a time before the problem, full system restore (it hurt bad when my 'new' machine came up with that little X)

when the error is up, if i look in device manager, there are no options at all for sound card, game controller, video.... also, it means not only do i not have sound, there is no device to update drivers for.

also, when the error is up, it also causes the Hp Quicktouch On-Screen Display to stop working (is this because the drivers are shared or something?)

stranger still, when the rare chance i do have sound and god's love shines on me, the HP Quicktouch On-Screen Display issue goes away. However i lose the ability to use the headphone jack! (this was just once that i noticed, and since the aforementioned full system restore i have only had sound once and the headphone jack worked, so there...)

Hey, guys.

I've been having that problem for a while now, but I could always just system restore back to a previous state and my sound comes back. But now, it seems that when I tried to do a system restore, one wasn't available.

I've done everything that I've searched on, like disabling/enabling sound card, uninstalling and installing again. None of those seems to work.

Since my system restore sets it back before an update is installed, then I think it's because of an update. And the most recent update since the Red X was an update for windows defender, and I can't uninstall the update, or whatnot.

I'm getting really desperate here, guys. Please help.

Thanks in advance.

I run Windows 7 Home Premium x64.
The sound card is Conexant SmartAudio HD.

A:Red X on Volume Icon, "No Audio Output Device is installed."

If it's a Windows Update you should be able to uninstall it, at least if you remember what number it was exactly. "Control Panel" > "Programs and Features" then at the top left click on "View installed updates", the updates you installed, at least via Windows Update, should now be viewable. Then find which one it was and uninstall it, should be easy enough.

So Windows isn't acknowledging your sound card in "Device Manager"? If not go to Conexant's website and search under "Audio Solutions" or google for any drivers that may suit your exact product. If it is acknowledging your card. . .I don't know. If it's not onboard then it wouldn't be able to be disabled in your BIOS, unless you have an onboard sound AND a sound card, and they're conflicting? If so you might have to disable the onboard audio perhaps?

Greetings and salutations.

I recently upgraded an Acer Aspire 3690 to Windows 7 (32bit) and everything went well, almost. See, for life of me I can't get audio to work. (That old chestnut.) The speaker icon in the notification area displays the white cross/red circle and informs me that "No Audio Output Device is installed". Fine. Okay. Just a driver problem, right?

Well, Device Manager is showing no discrepancies and the two devices associated with the Aspire's audio chipset (Conexant) are installed and happy (Modems/HDA CX11270 Soft Modem, and System devices/High Definition Audio Controller). But there is no entry for Sound, Video and Game Controllers, and that's what concerns me. Acer's driver support page for the 3690 tells me that Realtek powers the audio, but regardless of the potentially compatible audio drivers I've tried to install (most of the Conexant drivers fail with "Driver installation failed: could not find the MEDIA device for this driver" and the Realtek drivers either have no effect or BSOD the machine) I've had no success.

Now if I was running XP then MUAA would, I'm convinced, resolve the issue, but as far as Windows 7 is concerned I'm at a loss. Best I figured, the Realtek drivers should latch onto the High Definition Audio Controller then provide an Audio Output Device, but nothing's happening. I'm convinced that the physical hardware's fine because the Soft Modem diagnostics provide feedback, and the BIOS has been updated to 3... Read more

A:Acer Aspire 3690 w/ Conexant: "No Audio Output Device is installed"

I'm assuming you upgraded from Vista/XP. With and upgrade to a different OS and there are devices that don't work right away with the latest drivers tells me that the BIOS for the MOBO needs to updated/flashed. I would start there first. Sometimes the old BIOS are just not compatible with a new version of an OS.

Hello all!

So, I've just installed a fresh version of Windows 7, coming from Ubuntu 10.04. Everything seems to work smoothly, except for the little problem of having NO SOUND! I've tried everything I can think of or find anywhere on the internet, and nothing seems to be making any difference. The sound symbol on my taskbar has a little red circle with an x, and it states "No audio output device is installed". I've downloaded oodles of drivers (realtek, ones from HP, chipset driver for intel as well as the nvidia one, ricoh card reader driver, etc., all 32bit, which is what my win version is); some will install, some come up with errors, but neither seem to make any changes. Through device manager, I've disabled/enabled, uninstalled, deleted, had it check for drivers. I've used windows update to see if perhaps it had any solutions. Nothing seems to work. Does anyone have any advice/ideas I could try? If you do, please use layman's terms to get there. I'm usually very good at troubleshooting, enough to get by with few problems most of the time, but I'm not up on all the technical terms. I can include screenshots of anything if it would help. I am on a Compaq Presario V3020US notebook, with an intel centrino duo processor. I'm not completely sure of other specs, but if you know where I can find them, I shall look there. ANY help would be appreciated. Thanks in advance!


A:"Audio output device not installed", code 10, presario v3020US problem

I notice you mention the chipset drivers. In most cases the chipset drivers must be installed before installing sound drivers. If you haven't installed in this order, give it a try. I've also seen cases where the install was not initially done with the correct install sequence and after many different tries, it finally will take a new/correct sequence install to get everything working. On many PC's the correct install sequence is (1) Install Windows (2) Install motherboard chipset drivers (3) Install device drivers including video, sound, ethernet, etc. The chipset drivers are key to a successful install as one of the prime things they do is define (identify) all the devices on the motherboard.

Also, it could be a BIOS problem. Make sure the audio is enabled in the BIOS. You may want to reset the BIOS and see what that does. Check the Compaq BIOS resetting procedure (on most desktops you can just Power off the PC and remove the CMOS backup battery for about 10 minutes, but that's not alway easy on a Laptop).

I recently tried installing a program a friend of mine gave to me in a cd, but it ended up messing up my computer, After installing it, my computer kept showing this blue screen saying windows had been shut down to prevent damages. After awhile, it came back normal but I found out that there was no sound playing on the computer, the little speaker icon has a big red X mark and it says " No Audio Output Device is Installed", and Im not sure why, I;ve had this computer (Hp Pavillion dv6000) with Windows vista and I've never had a single problem with it until now. How can I get my sound back?

Help will be really appreciated! Thanks!

A:Solved: "No Audio Output Device is Installed"

Sounds (excuse the pun!) like an HD Audio Driver issue. I'd go to the HP website, search for your box and click the drivers and updates link. Download and install the Audio Drivers and reboot. That should solve the problem, but if it doesn't just post again and we'll have a re-think...

I used Macrium Reflect to clone a hard drive with some bad sectors to a better working one. I had to do some registry fun times and get the new C: drive to actually be a C: drive (that was a fun activity.)

After I fixed that as well as a wireless problem, I still cannot figure out what is going on with my laptop's onboard audio. Windows says "No Audio Output Device is installed." and a red X near the volume icon in the taskbar. When I click, troubleshooter comes up, and that tries to fix the problem "Audio device is disabled" which fails. When I right click, I can open up the Playback devices window and I see my main audio device, enabled as default. When I open that and click properties, it looks fine, but there is nothing in the Levels tab.

I have also tried reinstalling the audio driver multiple times, as well as the Mr. FixIt that Microsoft has, which reports that there is both a Low audio device volume and Audio device is muted, neither of which gets fixed. The device shows up without any problems in Device Manager.

What is happening? I'm good at computers (well for the most part...I did fix the drive lettering issue!) so I will be willing to do anything at all. My computer is a Lenovo T61 running Windows 7 Home Premium. The chipset is a SoundMAX. Any thoughts? I'm thinking it's all software because my sleep chirps and boot beeps when my hard drive decides not to init properly (???) all play through just fine.

A:"No Audio Output Device is installed." after HDD clone

If you did clone properly... it is an exact copy... so works the same. Did you clone all partitions or only 1 or 2? Was old drive also connected when booting from new disk? Normally macrium clone modifies ALL references to old disk on the new created disk. It does it even if you clone only one partition. After booting from cloned win7 you only have to adjust drive letters refereing to old disk. But since you removed the old faulty disk, this is unnecessary as well.

Don't know what happened. All drivers, documents,programs should still work! Did you clone without errors? Did you disconnect a cable accidentally when replacing harddisk?

Do you hear no sound at all? The beeps on boot are from internal speaker!! Not the soundmax

Hey fellas,

So i decided to upgrade from XP pro 32bit to Windows 7 Ultimate x64 a few days ago.
Thats when my troubles began. Did everything by the book, clean install , install motheboard/vga drivers properlly.

Thing is i got that little devilish x on the speaker down right corner and since then i've looked over 500 solutions over the web forums including many bios changes like enabling and disabling the onboard HD audio and bios update also tried to install several audio drivers of my motherboards onboard sound chip like from other software or 32bit softwares.

Nothing worked and its all due to my system can't recognise the audio chip since im always getting "We can't find HD audio device" when i try to install the drivers.

In device manager i can only spot one option that might be the sound card and it goes by the name "High Definition Audio Controller". I've tried disabling it but nothing.When i try to uninstall it windows 7 automaticlly installs it back.

The motherboard is an ASRock P43DE with the VIA VT1708S audio chipset.
(i've checked on my motherboard and i noticed 2 chips near the audio panel. one saying VT1708S and another saying Realtek. But the Realtek chip might be of the LAN controler not sure about that)

In playback devices and recording deviced i get no option, complete black space.

Hi, I was using my computer today and I left it alone for a short while, then when I came back suddenly the sound was not working, even though the volume was turned all the way up. I restarted it a few times, and eventually the audio output device was gone (there was an x in the icon instead of sound waves, and when I hovered over it it said "No Audio Output Device is installed"). I also did a clean reboot, which didn't work. I went to the control panel, clicked Sound, tried right-clicking where it said "No audio devices are installed" so that I could choose to show disabled devices, but that was already enabled. I went to Device Manager and clicked "Sound, video and game controllers", but the only thing in the dropdown was "Bluetooth Audio Device". Does anyone know what I could do about this?

I have a toshiba satellite U300 laptop, vista home premium 32 service pack 2. About 6 months ago I got the notorious red x through the speakers - I fixed it by re-installing the realtek audio driver. About a week ago the problem re-visted. At first, I uninstalled/reinstalled the driver which brought the speakers back, but everytime I turned the computer on the sound was gone again.I did this at least 8 times in the last week. I did system restore numerous times - to the point that now it doesn't even go back to a point when the audio worked. Now even this doesn't work and no audio device registers under sound in the control panel or sound, game controllers in device manager. I've read the forums on this for hours and tried many things since (including cleaning the disc, defragging etc.) The latest thing I have done is run the system file checker (sfc.exe) and got back several errors which it did not fix - maybe that's my problem?? I have no idea (although I have read the "how to analyze the log file entries) what to do with these results or what to do in general. I still have no sound after spending hours reading and trying to help myself. Can anyone help?

A:recuring "no audio output device is installed"

since no one seems interested in answering my question - I will answer it myself:
After spending many many hours on forums and support sites and trying all kinds of things (most of which were incredibly complicated techie remedies) I found nothing which helped me but thousands of other windows people with the same problem or a variation thereof. Until, by some miracle, I found a simple suggestion on yahoo answers: "...go into the control panel/Users and turn off user account control. After I did that the driver installation was successful..." and voila after more than a week of silence I have sound!! Worth trying

I have a Gateway GT5628 Core 2 Quad desktop. Vista Home Premium. It has on-board sound (which is enabled in the BIOS), and worked fine for the month I've had the machine until a couple of days ago. We had a power outage, and when the system came back up, I had a speaker icon in the system tray with a red X saying "No Audio output device is installed".

The system does not seem to realize that a sound card exists. It no longer shows up in device manager. Also, "Sound, video, and game controllers" is not showing as a category in device manager...was this removed in Vista, or is this part of my problem?

I talked to support at Gateway, and they told me to reinstall the drivers. As I expected, the drivers won't install because "Audio device not found". They then told me to do a Factory Recovery.....no thanks. I've spent too many hours tweaking this thing! Do you folks think a Factory recovery would do anything? To me this seems like a hardware problem. If the machine can't see the sound card now, it's not going to see it with a recovery either, right?

Plus, I already ran System Recovery once! The system blue-screened like crazy when I first got it. After installing all my software, I realized that SP1 was not installed. It would not install no matter what. I had to do a factory recovery, then install SP1, then re-install all my software!

FYI - I have the newest system BIOS installed.

Thank you for any tips!

A:Solved: No audio output device is installed - "Sound, video, game controllers" option

Sounds like the power outage did something not so nice to your PC (investing in a UPS is a good thing). It sounds to me like some sort of hardware issue at this point.

I would recommend opening the case up and seeing if any of the capacitors (little can like things) on the motherboard look like they are distended (look like they are bulging out or exploded), also do a sniff test and see if anything smells funny.

Hey, I recently installed an update for Windows Vista and it all went smoothly, but upon restarting I had no sound (volume icon in bottom right has a cross next to it) and highlighting it makes it say "No Audio Output Device Is Installed" despite having inbuilt speakers.

I can't do a system restore (very long story, my last thread explains it), so is there any way of getting my sound back in another way?

Thanks guys,

Hi, guys.

Been having an issue that I've been trying to solve for quite a while. I have an old Compaq Presario SR1750NX that refuses to acknowledge audio devices. It was on Windows XP at first and all the icons in the device manager had a yellow exclamation mark with error 39 (corrupted) in the device status. Since then (last night) I went ahead and upgraded it to Windows 7 Ultimate x86, and the save four devices show up in the device manager. The difference is that there's no error showing yet no audio devices show up in the Sound menu. Plugging in speakers in the various ports does nothing. I even went as far as swapping out the motherboard for a different one I had and the same result. Figured it was a hard drive issue so I formatted another old one I had and it's as if I did nothing.

Here are some images. I can provide more if necessary.

This image said "High Definition Audio" at first but I downloaded a set of NVIDIA drivers and force installed it for all four of these.

A:"No Audio Output Device is installed"

Disregard this thread. I found a source for drivers for this model and the BIOS update fixed it. Marking as solved and linking it for any Googlers out there.

First you need to findout if the laptop means the soundcard is not installed or it could mean that the OS is not detecting your speakers plugged in. To determine this you will need to go to control panel and select classic view then open Sounds. Make sure you have the speakers plugged in the CORRECT audio out jack and then go to the playbak tab and make sure it shows "speakers" in the white window. If it does not than right click a blank spot in that white window and select " show disabled devices. If the sound card name is not in that white window you will want to go to the device manager and make sure the soundcard is listed in there under sound video and game controllers. If it is not than that means windows doesn't see the sound card and it is more than likely a defective card and needs to be replaced. If it is in there right click it and select uninstall, check the box to remove the software for the device and then after the driver disappears you nee... Read more

Hey there! Maybe I'm missing a quick and easy fix but I'm somewhat at a loss as it stands. My laptop (Asus X555L, Windows 8, 64-bit) woke up from "Sleep" but suddenly wouldn't play any sound. A small cross appears on the speaker icon with "No Audio Output Device is installed" appearing if hovered over.

The troubleshooter didn't give much indication so my instinct was to uninstall the Realtek HD Audio driver and restart the laptop in the hope that my laptop will sort itself out during the reboot. However, the icon appeared the same and no audio played, to make matters worse, it seems it did not reinstall the driver and no longer appears in the Device Manager.
My next attempt was to "Add legacy hardware" - this resulted in another issue. Whenever the driver was ~75% installed, I was hit with a BSOD with the error "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (RTKVHD64.sys)". On the off chance that this was merely coincidental, I attempted to install the legacy driver once again but the BSOD kept coming back at the exact same point of installation.
This brought me to my next potential solution - downloading and installing the driver manually. I tried drivers from two different sources, Asus and Realtek, to no avail. The installation wizard runs smoothly all the way until the end but after rebooting, there is no difference at all!

This brings me to my current position. Since I do quite a bit of video editing, the sound is v... Read more

Recently purchased a Hp pavilion a6123w desktop pc with Vista(32), everything worked fine for the first few days but then for some unexplainable reason i lost audio. I tried to run the Hardware Diagnostic Tool but when I ran the audio test I recieved a warning message that states "Audio device has been disabled by user or otherwise not available" so I wasn't able to complete the test. I then and made sure that windows audio was started in "services" and it was already started. Ran Hp update...everything is fine, ran windows update......everything is fine, re-installed the original Realtek High Definition Audio Driver from the Widows Help & support Manual in Vista and yet still "no audio output device is installed" when I hover my cursor over the speaker icon by the clock and definately no audio from speakers. The speakers are btw plugged in and in the appropiate place. I even tried system restore and nothing.

I've poured through tons of messages on several different web sites and seen that many have sound issues with Vista but yet no applicable answers for my problem. I am at wits end and thinking about just downgrading and popping in my recovery disc for Windows XP that I had on a older pc into this one. Would that even be advisable?

Any advice would be GREAT! Thanks in advance!

No idea what is causing the issue, but one day when the laptop was turned on, there was a Red X over the volume icon and sound wasn't working at all. Device manager shows that no sound device is installed, just as the icon says. I tried installing the sound drivers for the machine from Toshiba with no luck. I restored to a time at which the sound worked, but that obviously did nothing.

"High Definition Audio Device" is listed in my device manager under the "System" tab with the yellow exclamation point. I tried uninstalling that, disabling it, and reinstalling the drivers in every combination in Safe Mode and not.

Some other things popped up during the same exact time as well. The laptop used to Sleep when you closed it, but now I close it and the fan revs up and it won't turn on so I have to hold the power button down to get it to power off and then on again. Also, the USB ports have stopped working entirely.

According to the Toshiba forum, this is an ongoing issue with the Satellite series of laptops, but I wanted to see if you guys had any input.

MalwareBytes has nothing to say about the issue.

Hey Everyone,
I have recently finished building myself a P.C. When I first used it I noticed it had no sound. There was a cross over the sound icon and it said no audio output device installed.

On running Dxdiag there seems to be nothing at all under "sound", even though I know I have integrate realtek HD audio.

Under system information (msinfo32), however, it says that under sound device there is a sound card, but it says "status: error".

In device manager, in sound, video and game controllers, it has the realtek card there, but with a yellow exclamation mark next to it. Under properties it says that it "cannot start. (code 10)". It says that the drivers for it are up to date, but even so I downloaded the most recent realtek audio driver to make sure. This made no difference, although I am not sure it installed properly as device manager still says that the default windows driver is in place.

I have speakers that work and I have checked alot of things to see if they are okay, including clean installs and the such, but my computing knowledge is extremely limited and I was wondering if anyone could suggest anything I could check or do or buy to make my sound work.

Thanks very much for your time, Telstar

code 10 sounds like a driver problem. Have you tried to go to properies and uninstalling the hardware then restarting the pc. maybe it will find the driver that you dloaded from real tec. What version was that because I do see a driver for win7 x32 listed for your device and that is v r2.31 ?

Hiya, so my problem is that i have no sound, haven't had for a while now.
When i hover over the speaker icon it says "no audio output device installed".
I've tried going to device manager and beside where it says "Realtek AC'97 Audio" is a yellow triangle with an exclamation mark inside. I have tried clicking update driver software and scan for hardware changes.
I have been googling this problem for ages to try and find a solution but anything i can find doesn't work. If anybody could give me any suggestions on what might be wrong and how to fix it i'd really appreciate it.

I don't know much about the computer, it was given to me and i'm not much of a computer wiz. But if you need to know anything i will try to answer.

Hi Jodie

Are you running Vista or Win7? What version?

In the 'start search' box type dxdiag. When the icon shows up at the top of the list, click on it to open it. Next let it download a .txt file
Click the "Save all information" button. A little icon that looks like a notebook page will be put on your desktop. Copy and paste the information from that log and post it in this topic.

I have a HP dv6910us laptop and since 3 days ago, have been getting the message "No Audio Output device is installed" when I hover over the sound icon in the dock. There is also a red X present. This kind've happened out of the blue while I was watching a video on Hulu. Everything froze and firefox stopped responding. I did a restart and the red x was there with the "No Audio Output device is installed" message. That's when I found out the speakers and headphone jacks stopped working.

I've tried going into device manager and looking for the driver, but the Sound, game controller, video section isn't there. I've troubleshooted sound before and I've updated the driver through there before too. I went to HP's website and found the driver under the notebook support section. When I installed it, it first told me the files being installed already existed. I allowed it to overwrite, but right after it showed an error saying "No media device for this driver was found."

I further went on to performing a system restore to 5 days back but it did not help.

When it happened I was on Windows 7. The factory installed OS is Vista so I went on to performing a clean install of Windows Vista. After it installed, I opened Windows update and got all the drivers but was met with the same error when I tried to install the Conexant audio driver. "No media device for this driver was found."

I re installed Windows 7, and once I finished, I logged on, and tried to watch a video online, and realized there was no audio.

Hi, I am running a 5 year old HP pavilion dv6919ca laptop. I use Bell internet who just recently switched their security package over to McAfee and I installed it several months ago. I have been having sound problems for about two months, prior to this everything worked perfectly. Now most of the time the speaker icon in the task bar has a red x through it and states "no audio output device installed" and there is also no sound or game controllers listed in device manager. At other times the laptop starts up with sound and seems to be working properly but within 20 minutes of watching a video the sound will disappear and when I try to investigate the computer gets really slow or hangs up IE. I have restored my pc back to factory after a ransomware attack but the sound problems after this were the same. My sound is a Conexant high definition audio device. I have reinstalled the drivers-no change. Something is turning off my sound and I don't know how to fix it. Please help.

A:"No Audio Output Device is Installed"

Let's see this:

Press and hold the Windows button + R.

In the Run box, type DEVMGMT.MSC and hit Enter.

Click the + next to the Network Adapters pane so it expands, showing installed hardware.

Take and screenshot or make a list of the devices listed here and include it in your next reply.

Take note of any !'s, ?'s or X's.


Depending on which device is in your machine, below are the latest drivers for the possible sound cards for your machine:

Conexant High-Definition Audio Driver

Realtek High-Definition Audio Driver

Once you've determined which device is on your system (it will be in Device Manager), download the appropriate drivers and install them.

Reboot your system.

I received my Acer Aspire One notebook with Windows 7 Starter last year for Christmas. Not a week later, the sound would spontaneously stop working, often while I was in the middle of listening to music in Winamp. For a few days, restarting would fix the problem immediately, but then it stopped working entirely.

The speaker icon in the lower right is covered with a red X symbol, and hovering the mouse over it I get the message "No audio output device is installed."

Googling the problem found me lots of forum topics about similar issues on Windows 7, Vista, and XP, but most of those were solved by going into the device manager, finding the Sound, Video, and Game Controllers option, and disabling then enabling the sound card. But I tried that, and that option is not even listed in my device manager. If I go to Control Panel > Sound, the Playback tab just says "No audio devices installed". It's as if my computer forgot it had speakers. Of course, headphones don't work either.

I tried system restoring and eventually reinstalling. Sometimes the problem would resolve on a restart and work fine, and when that happened the device appeared where it belonged and I updated the drivers. But on the next restart, the problem happened again. I figured out how to flash the BIOS, and it still didn't work.

About a month later the problem went away again and didn't come back. But now, five more months later, it seems to be back again for good. If I... Read more
