Sound/Mixer icon has red cross. No Audio Output Device is installed.

Q: Sound/Mixer icon has red cross. No Audio Output Device is installed.

Windows 7 32-bit won't play sound.

Device Manager\Sound, video and game controllers\High Definition Audio Device ok.
Double click and window says:
High Definition Audio Device Properties\General: Device status says This device is working properly.

Speakers are plugged in and make a crackle when plugging in to correct holes.


Preferred Solution: Sound/Mixer icon has red cross. No Audio Output Device is installed.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Sound/Mixer icon has red cross. No Audio Output Device is installed.

If it's shown as "working properly" in the Device Manager, the speaker icon you have can also be because the sound is muted.

You show "High Definition Audio Device" rather than the actual sound device which suggests you have the generic Windows/Microsoft installed sound driver rather than the actual sound driver from the motherboard vendor. In many cases the generic Windows driver does not work or work correctly.

You can try and uninstall/reinstall by RIGHT clicking on the entry for the sound and then LEFT click "Uninstall" (DO NOT check the box to uninstall the drivers) then restart the PC and when Windows starts it will detect and reinstall the sound. This fixes a lot of flakey problems.

If the uninstall/reinstall does not fix it, the next step is to get the correct sound drivers and install them.

I was deleting files on my computer yesterday for some spring cleaning and I may have accidentally deleted a program which controls my audio playback and recording. when I right click on the icon in the lower right corner of my home screen, It shows no disabled devices or disconnected devices are available. Oh, and for reference, I was only deleting from my documents files. I have already emptied my trash. I also had sound for the following four or five hours, but then the sound would go off after five or ten minutes of play. A few hours later, the sound completely stopped and that was when the message appeared on my sound icon. Thanks for any help.


A:Sound icon reads; No Audio Output Device Installed

A few quick comments for now:
Your description says you have SP1, is this updated? If yes, please install SP2, it has a lot of fixes and updates.
Did you try a system restore?
Did you do a Virus and Malware scan?

Here are some picture of my driver and stuff . Sorry for large pictures guys .

A:Windows 7 no output audio device installed red cross

Hello and welcome Kurosaki mate where di you download the driver from - the Windows feature (not a great fan) or the manufacturers - ASRock > Products > Motherboard > N68-VS3 UCC > Download (see the audio ones)

Plus in Device manager it does not look as if you have any yellow problem markers so am a bit perplexed.
Try the driver from the Asrock site and see just make sure it is the Windows 7 version (there are two).
Post back what happens.

Hello All,

This is my first time to this forum, so I'm not sure if this is the right place to post this or not.

I have a one year old HP Pavilion dv2000 laptop that came with Vista. We installed Windows 7 about 6 months ago or longer and I haven't had this problem until now, so I don't think it had to do with putting W7 on it.

Out of the blue when I turned my computer on the other day the sound icon on the taskbar had a red X on it. My first thought was that the sound was muted, but I checked that and then noticed when you hover over the sound icon that it says "No Audio Output Device is installed." And when you click on "playback devices" it doesn't show any sound devices.

Well, I searched all over the internet for a solution and installed drivers, used system restore and reinstalled windows even! But to no avail. I heard some other people with this same problem would get there sound back on and off, all of the sudden, and that's what happened with my computer. The day before yesterday the sound was back when I turned my computer on. And then yesterday it was off again.

So, now I have run out of ideas to try. If anyone knows of something that might work to fix this problem please let me know.

It's been like this for about 3 or 4 days now, on and off mysteriously.

Thanks for any help I get.

Hello everyone, i have seen this posted before but my problem is a little different. I can not even find what my sound card is or where it is. I have looked and looked and there is nothing on my computer to show it has a sound card. It did indeed work before i upgraded to 7 so it has to be there. It is a Gateway laptop MX6440. Thanks for any help!!

A:No Audio Output device is installed! no sound! :(

Welcome to seven forums Solidsimpson: Just a suggestion. Go to Gateway site and update all the drivers you can. If no 7 drivers are available Vista will do in compatibility mode Compatibility Mode Without knowing what sound device you have it is virtually impossible to point you to a solution. You might also want to go to device manager and copy and paste a screen shot of your device manager, so we can see what your seeing.Thanks Fabe

My laptop's sound isn't working, and when I mouse over the speaker icon in the corner there's a red X with the message "No Audio Output Device Installed." I've looked on other forums for the solution and here's what I've tried so far:

-I've been told to disable and enable the sound device in Device Manager, but there's nothing under "Sound Video and Game Controllers"

-I've tried to reinstall the audio drivers (Realtek HD Audio and Conextant HD Audio). The Realtek driver says it installed correctly, but it still doesn't show up in device manager or anywhere else and the "No Audio Output" message still persists. The Conextant driver gives me the error message "Cannot Find Device" when trying to install it, but I've noticed something weird: I can see a Conextant HD Audio thing under "Add or Remove Programs".

-Windows Audio is running under Administrator Tools, I've checked.

-I've done a system restore back to factory settings and it still doesn't work.

My laptop is a Hp Pavilion dv6700z with Windows Vista Service Pack 1. I think a windows update might have screwed it up; I can hear a popping noise when plugging in my earbuds and I can hear the error beeps under system setup, so the speakers themselves work. Can somebody please help me out?

Normally using my laptop last night. When i opened it this morning. I have no sound and the deadly X red mark on my volume on my lower right screen is present.

It is obvious that this problem (no audio output device installed) is very common to many. Reading through hundreds of threads saying i just have to find "sound, video game controller" and re install it. The problem with mine is that i dont even have that kind of tab on my device manager? how come?

(By the way...when i open my Device manager. I can see under Other devices that i have 3 Base System Device that has a yellow exclamation marks on it) FYI

I tried looking for sound programs in my computer (through search, through dxdiag, etc.) and i cant even find a sound driver. Because of this, i go to Realtek and installed the newest high definition audio codecs for 64bit windows 7 which version is R2.71 update 2013/4/8. Feeling confident that i can now install it to my device manager...i tried doing it. To no avail, i cant install it...this is the procedure that i am doing...

1. Device manager
2. Add legacy hardware
3. Next>choose Install the hardware that i manually select from a list. Next
4. Choose Sound, video and game controllers

A:No audio device output installed, no sound, video game controller...

The first approach, since it worked and then the next day didn't is to use the System Restore and restore the PC back to an available restore date that is Prior to having the problem. This fixes many problems, including your problem many times.

System Restore can be accessed from Start/Programs/Accessories/System Tools. System Restore will not delete any user data or e-mails.

Hi, I am new to this forum and desperately in need of help with sound. One day I opened my laptop and the sound was gone. The error on the icon is "No Audio Output Device is Installed". I am using SONY VAIO VPCSA35GH (Available in Asia Pacific region).

FYI: I have two display adapters. AMD Radeon HD 6630M and Intel HD Graphics Family.

On the device manager panel: I've got only one hardware in "Sound, video and game controller" section, which is "Intel(R) Display Audio".

MY OS: Windows 7 Professional x64

Here is my attempt to solve the problem, but to no avail:

-System Restore: I tried to use system restore to the point it worked fine. It does not work at all and now my restore point has gone too.
-Install driver from Intel Download center : Refer to my graphic card, I tried to download new graphics driver for my motherboard. It doesn't work. I have downloaded from this website: https://downloadcenter.intel.com/Sea...ng&ProdId=3319
-Install driver from SONY VAIO support center : I tried to re-install Audio Driver and also Graphics Driver from this website. Support for VPCSA35GH : S Series (VPCS) : VAIO&reg Notebook & Computer : Sony Asia Pacific and it also doesn't work.
-Look it up on BIOS : My BIOS does not have any option regarding to audio issue.

My two attempts to re-install the drivers were done in safe-mode. Could you please help me with this problem? I really have need to use audio with my project.

A:Problem with sound: No Audio Output Device is Installed. LAPTOP: VAIO

The Intel Display Audio is ONLY for HDMI Audio and not the regular PC audio. The first thing to check is the BIOS to verify the on-board audio is enabled. Normally, if the on-board is enabled in the BIOS but no hardware specific driver is installed Windows will install the generic "High Definition Audio Codec" driver. As this is not happening, it suggests either it is disabled in the BIOS or remotely it has a hardware problem.

If it is enabled in the BIOS, first thing to do is reinstall the motherboard chipset drivers from Sony. If the chipset drivers are corrupt all the devices could be mis-identified. Restart the PC after installing the chipset drivers and see if Windows detects and installs the High Definition Audio Drivers. If it still does not install, either the Windows 7 Operating System is corrupt and you will have to do a complete new install, or there is a hardware problem with the sound chip.,

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?

I have gone to system restore
Dont have a clue what to do next
Could anyone offer any assistance

Many thanks in anticipation


A:Volume mixer - no audio device is installed

no so confident about this answer, just a wild guess, but have you tried going into the BIOS and checking the sound card is enabled.

When the computer turns on look out for a message that says something like press <DEL> <F12> <F11> to enter BIOS/SETUP

When your in there use the arrow keys / tab button to navigate and look for something that says AC97 or onboard sound, or anything that hints at sound and check its turned on.

Other than that, as strange as this sounds, try plugging in some headphones into your machine and seeing if it says the audio device is available (newer windows/drivers can detect if speakers are plugged in, it may be this that is faulty, this may find it out)

Another option to consider is to download Ubuntu (linux) just google it, and burn it to CD/DVD. You can use it to load up linux onto your computer (it runs off the CD, it doesnt touch your files)

Ubuntu will automatically install sound drivers when it loads, see if you can make it make a sound, if so you know its windows thats wrong. It might be worth reinstalling windows or A final alternative is start the computer in safe mode (hold f8 just before the Start Windows screen shows, if in doubt, turn the computer on and just hold it) when in safe mode go into Start > Right Click Computer > Properties > Device Manager and then delete all references to your soundcard, restart and reinstall your soundcard.

I have a windows 7 64bit computer that runs realtek hd audio and nvidia hd audio.

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?

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.

Hi to all.

I am running Windows 7 Home Premium on my Dell Inspiron E1505.

I have had no problems with it for several years; however, recently my computer has booted with a red 'X' on my audio and tells me that "No Audio Output Device is Installed." I checked my Drivers and my High Definition Sound and 2 Base System Device drivers have Yellow Question Marks by them. I tried to update the drivers manually but it says Windows Cannot Find Support for your Base System Device and it says my High Definition Audio is already up to date. I have also tried uninstalling the drivers and rebooting Windows to let the system automatically search and update the drivers. This too has failed. I do not have my Windows 7 disc available at the moment to be able to do a clean install.

No sound.
Little speaker with the red 'x' appeared yesterday
I have gone through the whole update drivers circus to no avail, my laptop can't detect that it has speakers built in so it doesn't bother finding a driver for them.

This is where I am at:
- Intel Display Audio is the only driver installed for sound
- This means that sound works when the laptop is plugged into an HDMI
- When HDMI is not plugged in, the computer cannot find the built in speakers.
- I have Linux on this system and audio does not work there as well

I would call this a broken chipset, but the fact that the computer still processes audio with the HDMI cable attached is confusing me. Also, the 'audio board' for this laptop has 2 usb ports attached to it, and those both work fine.

Any help would be appreciated

Hi all,

I've been trying to fix my computer for the last 4days now and have trawled google and all the sites its led me to for what seems like forever. Anyway, heres the problem:

I do not have a separate sound card;
it is integral to the board (ASUS A8N SLI deluxe)

I had sound on Saturday morning, I fell asleep and someone else used my comp and when I woke up, no sound, no master volume in the system tray and no audio device detected.

When I try to play, from the hard drive, an mp3 or mpg, for example, I get no sound.
(I do get the video from the mpg or wav, etc.) I get:

"Windows Media Player cannot play the file because there is a problem with your sound
device. There might not be a sound device installed on your computer, it might be
in use by another program, or it might not be functioning properly."

When I try to play something from the RealTek player I get: "Cannot play back the
audio stream: no audio hardware is available, or the hardware is not responding.

A:No Sound: No Audio Mixer Device Available, No Attempted Fix Works

hm there should be somewhere in your bios to enable/disable onboard audio...i would give that another check first.

you said that device manager says that its working correctly - what exactly is working correctly?

Alright, I give up. I've tried everything I can think of to fix this damned problem so now I'm left with no choice but to seek outside help. So, last night I updated windows after a minor leave of absence from doing so. and once everything was configured my computer started insisting I had no sound drivers installed. There's a neat little red X over my audio icon and everything. I checked the control panel, and there are in fact drivers installed. I tried updating them- still nothing. I tried uninstalling and reinstalling them- still nothing. Tried a system restore, that didn't work either either. So, suggestions? I'd appreciate any help you could give me.

Welcome to SF. Could you do us a huge favor and fill out your system spec's so we can get a better idea of components. I trust that no connections were changed all you did was an update?

I had this problem since late October. My sound just randomly stops working. I tried to reinstall the driver, did not work. I tried to install the driver from the site, did not work.

HP dv6904ca

Conexant High Definition SmartAudio 221

A:No Audio Output Device is installed

Sorry that you are having this problem. It appears to be a common problem with no real fix. I have not found a resolution for this and posted this same question the other day. No one has really been able to help.

I'm becoming a pro at troubleshooting my laptop ....
If you go to Start... type system in the search.... look for System information and click on that.
Click on Software Environment, System drivers. Once that opens up..... scroll down til you find the Conexant Driver. The driver is there, but it is stopped. It should probably say Conexant UAA Function Driver ...... and if you scroll across that line.... you'll see where it says 'Stopped" ....

The problem is getting it restarted. If I can ever figure this out and find out why it keeps stopping ... then we'll be in business.

If any of the guru's on here happen to see this..... please give a little insite.

I recently had to reinstall Vista Home Premium 32bit.
I have everything back in place except the audio

The Audio is listed as a
5.1 CH windows vista premium level HD audio
(via vt 1708S audio codec)
and I believe is integrated into the motherboard.

I have a red cross beside the speaker icon on the task bar.
And when I hover it say

"No audio output device is installed"

However, when I go into the section of Device Manager under Sound etc
it is listed as High Definition Audio device
and using 'properties' it tells me the device is working properly
and has the correct driver

I have tried updating the driver,
I have uninstalled and reinstalled the device
I have search for new hardwear
I haver tried the microsoft repair tool to no avail.

It was working perfectly, I reinstalled Vista, and it ceased to work.

Any suggestion of where to from here would be appreciated.

I have an old Dell Dimension 4550. It used to run XP but was recently upgraded to Vista. Now there's no sound anywhere. None detected anywhere. Device Manager has no "Sound, Video,..." I tried to install drivers from Dell website and Soundblaster is not compatible. Any ideas???

A:No Audio Output Device Installed

You should have checked the Dell website for the driver situation before going ahead with the OS upgrade.
Dell doesn't support Windows Vista on the Dimension 4550 (no compatible drivers) and only Dell has the correct drivers for Dell computer's.

As it's not a laptop you can fit a sound-card into a the AGP or PCI expansion slot. It will be supplied with Vista drivers on a CD if you buy one in a retail box and not a bare OEM one. You're just fortunate it's not a laptop as they don't have expansion slots.

Uninstall the driver and then install again.

Just pulling the plug would not normally due this. Is the speaker or the cord damaged?

Up until yesterday, I had sound . I was playing a game and then the sound disappeared. A Red X appeared on the sound control. I shut down my laptop and everything started again.... then the sound stopped and the Red X appeared again. I have shut down more times than enough trying to rectify the problem to no avail.

My laptop is an HP Pavillion dv9810us running Vista as OS.
The sound card is a Conexant HD Smart Audio 211.

I have been searching to resolve this problem and some other issues that started a while back. The initial problems were the webcam and the CD/Rom drive stopped working. I got them back and they worked a few days and disappeared again. I have run MrFixit and nothing. I get the messages that the drivers are missing.
I have tried updating the drivers and redownloading... nothing seems to work

In troubleshooting, I was able to find a way to view hidden devices in Computer management. I did so.... and it shows my missing devices... webcam/ cd/rom / sound . When I click on those devices... the icons are grayed out showing they are inactive. I cannot activate them.

Before uninstalling and rebooting my laptop to see if this will reinstall the device drivers.... what am I missing and how can I get all three of these devices to be functional again? I have some online tutorials to do... but can't do them because of the 'no sound' . I am truly aggravated by this.

It appears that this is a common problem that has not been resolved by MS.

All the plugs were in the same ports, but when i started my computer the error message "No audio output device installed". I am currently using a samsung televsion as my monitor. the sound is connected from an AUX cable. i have tried system restore and uninstalling then reinstalling the audio drivers, but no luck. On the Sound panel it says "Speakers, Realtek High Definition Audio, Not plugged in"

Hey there, i need help! I have an HP windows vista and it worked fine and dandy until a couple weeks ago. The screen didn't turn on and i got an error code from the computer saying that the video card i had was shot, which was a Nvidia GeForce 7500 LE.

So i get a new video card, Nvidia GeForce GT 440, and the screen works fine now, but all audio is gone now. There is an X symbol on the volume control in the corner on the desktop. It says in the Device Manager that we have 4 NVIDIA High Definition Audio drivers. But when i hover the mouse over the speaker in the corner next to the clock it says "No Audio Output Device is installed." I went to the Playback Devices and it says "No audio devices installed." I cannot access volume control, and the speakers are plugged into the correct jack. I also tried plugging the speakers into all the other jacks and it didnt work. I tried using headphones in every jack. All the correct drivers for the video card are installed and updated. Still no sound.

As far as i can tell, the old video card did not have a sound card on it and neither does the new one.

I've tried everything, i even talked to several different people at computer stores and they have no clue. I don't know how to switch to on-board audio, but i heard that going into BIOS can screw up the computer badly. I'm at a complete loss and am very frustrated. I don't know what to do!

This is my wife's sony vaio, and she has had this problem with no sound on her laptop, when checking the volume control it says no audio output device installed. In device manager it says that she has Intel display audio. I need major help here please.

A:no audio output device installed

You will need to reinstall the Sony provided sound drivers, as a first step. Go to Sony and get the drivers for the exact model PC. The Intel display audio is for HDMI, and not the regular PC sound.

Has it ever worked?

Hey .. I have a laptop and have a problem with my audio...
My laptop is an Acer 7520, and I have Windows 7 64-Bit installed.
Before continuing please read this thread since it describes my problem

I did the same things that guy tried..I mean ..I did everything possible to get the sound back.
I'm sure the Hardware is OK because sometimes the Audio starts working and when I restart it stops.
I don't want to format because I have very important stuff and can't copy them to anywhere ..
I also asked Acer and they meant that they can't answer because the original Windows ist Vista and I have
installed Windows 7.

Thanks for any help!

This is probably as simple as an audio driver. Can you tell us your computer specs so we can locate one for you?

Hello Carla,

Welcome to Seven Forums.

First off it is not wise to put an email address in your posts. It will attract tons of spam.

Was this an upgrade install or a clean install of Seven?

All right, I know this is a pretty common problem and it's probably been asked a lot, but my case seems to be a bit different than anyone else's. A while back I downloaded a registry file to try to get sound in safe mode. Stupid, I know. Anyway, it didn't work, but ever since then my sound has not worked in normal mode either. Earlier today I went to device manager and looked, and saw there was no Sound / Video / Game Controllers installed. Anyway, I went and got the Realtek Driver for my Gateway GT5676 and tried to install, and I don't know what happened, but it didn't seem to work. Then I attempted to install the Legacy driver and that worked, but now it's saying "the device cannot start (Code 10)"

I'm not really sure where to go from here. If you want I can supply a link to the registry file that seemingly screwed it up, and maybe we can work from there.
