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?

unistalled sound driver and restarted my pc installed it again and it did not work than I reinstalled again windows 7 ultimate and the same thing again .I dont know what to do now .

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?

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. 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?

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.

On my Dell OptiPlex 755 E6550 2.33, I've had intermittent issues with the headphone socket suddenly stopping working for quite some time,sometimes problem is auto detected and fixed, sometimes I download a driver or three to resolve. This time nothing is helping no matter what drivers I've tried. Have Win 7 Ultimate installed with just on-board sound. No sound or audio shows up in device manager? Are 755's fickle with on-board sound or just too many sound drivers installed? Any ideas please.

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.

Any help you could give would be greatly appreciated.

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.

From RealPlayer I get "Cannot open audio device. Another program may already be using
it. "

I have recieved this message: Cannot play back the audio stream: no audio hardware is available, or the hardware is not responding. (Error=80040256)

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.

You may need to upgrade your drivers. You can also run the sound diagnostics page to help pinpoint what the issue may be: http://support.microsoft.com/mats/no_sound/en-us

I believe this is an issue regarding an update.

I had this issue before and did a system restore to back before I had installed a certain program, and the issue went away.

Now however, I do not have a restore point that will go far enough back.

I started up my computer today and I was hit with the "No Audio Output Device is Installed" message, showing a red x circle by my speaker icon.

When I click on it it detects problems then attempts to install the driver needed.

Every time it attempts to do this it fails.

The driver is the "High Definition Audio Device"

Upon entering device manager everything related to sound has a yellow caution triangle next to it stating that...

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
I have tried the followingUninstalling everything on the "Sound, video and game controllers" list, and attempting to reinstall
Installing the realtek audio drivers from their site
Removing my sound card and attempting to use onboard sound

The sound card I'm using is an old sound blaster live card, I don't think I even need it, but for some reason I still use it. (perhaps that will become apparent)


A:No Audio Output Device is Installed

Try control panel(large icons) and going into your sound, and manage or view sound devices. If there is nothing in your output(playback), then thats a problem. If there is, then select your speakers/headset/anything you use that generates audo that is connected to your computer that. If all else fails, try a new soundcard

So I have a Toshiba Satellite L505 and the whole thing that messed it up I'm guessing was because the battery died, or something but when I got home, the battery was dead so I plugged it in and suddenly, there is no more audio. I looked online for several solutions including trying to find the device in Device Manager, the only thing I see is HD Audio Controller with a yellow mark. I'm almost positive that I used to have Realtek but its not there anymore. I tried going on the realtek site to re-download the device but at this point I get stuck because it downloads the drive that I need and starts up the wizard but when I restart my laptop, its still showing no audio.
I've also tried recovery mode and trying to recover to a past date before the battery died and still no success giving me a window that said that It couldn't complete the recovery. Any help would be welcomed and appreciated.

I'm pretty sure you guys have seen this before; sound icon with a little x over it. I tried Google-ing a solution but none of the suggestions I found there were helpful. I'm posting 2 pictures up to, maybe, give you guys an idea of what the issue can be.Additional information: the laptop at hand tries to install new drivers but fails everytime. No idea why. It tries to install a bluetooth driver.Any help would be greatly appreciated.

A:No Audio Output Device is installed...

1) What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?
2) Laptop drivers should always - and only - be obtained from the website of the laptop manufacturer. I suggest you go there and download the appropriate drivers and install them. You might want to start by downloading and reinstalling the chipset (or smbus) driver.

HP Pavilion Dv9700,no audio again. Operating on vista. Have tried to download drivers from hp support website with no joy. Help again please!

A:No Audio Output Device Is Installed

I found that several HP owners whose computers I service have issues with the "correct" driver from HP's site doesn't work. The error you are getting means that the driver is not compatible, so you will need to find either a previous version of the driver for you Dv9700, or you will have to fool around with drivers of other HP models close to your model number. That worked for me many times.

By the way, are you downloading the correct driver for your version of Vista?

Yesterday my sound was working fine, I walked away from my notebook for 15 minutes and came back and the sound icon had a red X against it. The error message when I hover over it is 'No Audio Output Device is installed'.

In Device Manager the error message for Realtek High Definition Audio is: This device cannot start. (Code 10), although there have been different error messages depending on where I am at with troubleshooting.

I have tried reinstalling RealTek drivers on the sound card, rolling back drivers, using sound troubleshooter, system restore etc with no luck.

I have also spoken to Windows support and they couldn't resolve the issue and suggested I contact the notebook manufacturer (ASUS). I tried doing this but ran into errors on their website.

Are there any further suggestions anyone could recommend that I try?

Some details of my system:

OS: Windows 10 Home 64 bit
Manufacturer/Model: ASUS X555LJ
Processor: i7-5500U
Ram: 8GB

Any help would be great!

Hello, I have exactly this problem :
No audio devices are installed
and in the end they say "to make sure that the power service is started and set to automatique", now my question: where ??? is this option to put the power service to automatique??? where can I find this in my Labtop?? Please step by step so I can find it. Thank you very much for your help ))

A:no audio output device is installed

They are talking about the services in windows and they can be found by typing services.msc after hitting the start key on your keyboard. like my pic below but I don't know what specific power one they are talking about. Do you have any that are named similar that are disabled? If it is the one I show make it set to automatic and reboot.

Okay well this just started happening like two weeks ago, I started up my computer and there was no audio, my friend told me restarting should fix it, I did and it started working. Well, now I have to restart my computer soon after I boot it up. The audio always comes back when I restart. I had Realtek under the Sound, Video and Game controllers tab but it's gone now, the program however is still installed.
I'm on a 64 bit Windows Vista. I've tried RE-Downloading Realtek drivers but it won't work, also tried the drivers in your Driver List but it says I need Administrative privileges or something and this account is the Administrator. Any help is appreciated.


This is how it looks before I restart.

And here it is after I restart.

Realtek doesn't even bother showing up anymore, instead it is replaced with High Definition Audio Device, at least I get to hear sound with that one.

I have been having this problem for about a month now. There is a red x over my sound saying no audio output device installed. I have tried everything I could find that worked for people on here. I have done the uninstall and restart and reinstall and getting the drivers etc. it keeps telling me no matter what I do it "failed". Even when windows tried fixing it. I have a hp pavilion zd8000 (yes i have tried hp's site) and it is a notebook. under my device manager it shows up with the yellow triangle with the exclamation point. I desperately want my sound back, help please!!

A:No audio output device installed?

I'd try the following:
1. Check to see that the sound is enabled in the BIOS.
2. Unistall the device from the device manager and let Windows find it again.

You may have a bad componet on your mobo that will require you to take it a local repair shop.

I have a laptop on which Vista Home Premuium, Service Pack 2 is installed.
Sometimes after a reboot, my sound symbol is covered by a red/white crosss with the message "No audio output device is installed".

In Device Manager, sound is not listed so updating/installing driver there is not an option.

The problem usually corrects itself after a cold boot but now even this is not working!!

Please help.

A:No audio output device is installed

I'd take that as a sign that the device is failing/has failed...and just try a cheap physical sound card.<<In Device Manager, sound is not listed so updating/installing driver there is not an option>>I don't believe that, since Windows will install some defaults whether there is a sound controller installed or not. Sound, video, and Game Controllers should appear in Device Manager. Installing drivers installs the audio controller.I would ensure that I had attempted to install the correct drivers...before I wrote the audio function off.Louis

Hi, I need help with my brother's PC. Problem with sound and "no audio output device installed" and red X on speaker icon. Went
to Device Manager = no "sound video and game controller" found?
Tried loading new realtek driver to no avail. Cannot do a re-
install as I can't find a Vista disc anywhere. Also, with this problem
everytime I view a picture file jpeg on a large scale the
computer freezes. I even bought a Driver Boost and that didn't
help as of now.

Apparently, these problems has been going on for more than 6
months now since the anti-virus program expired. I loaded AVG,
Ad-aware and Advanced system care a week ago to help out my
brothers pc. So far no luck except this forum - I hope...

I'm back at no sound and afraid to open any pictures as it will
freeze the pc. Any help? Where do I start now? This is my last week before
going back home.

What is a driver boost?
Start with a system file check.Go to start search and type cmd, hold shift and ctrl and press enter. An Administrator command prompt should open.
In the box that opens type sfc /scannow
If errors are found run it again. Restart your computer after running.

Realtek sound driver is here and sometimes needs to be run twice, once to remove your existing driver and again to reinstall.

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.

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.

Good day everyone!
First time here in the forum and in desperate need of help with my audio.
My audio dissapeared one day and unable to find a fix. I tried re-installing audio drivers and downloaded the lastest drivers from Intel's website and still no solution. Audio in BIOS is enabled and also did BIOS update.
"NO AUDIO OUTPUT DEVICE IS INSTALLED" and missing "Sound, Video, and game controllers" from the device manager.
Maybe a special driver needed? or settings?
Here are my specs:
Windows 7 Ultimate
Intel DG33TL MB using built in audio/video.
Audio chipset IDT.
Help me please please please!!!

A:NO Audio Output Device is installed.

DG33TL, welcome to the forums.

I would start with updating/re-installing the chipset drivers,

Intel? Driver Update Utility

then see if it shows back in Device Manager, and then install the suadio driver.

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.


A:No audio output device is installed

Hi alba100,

Let?s try run Microsoft fix-it to check if the services are enabled and drivers are installed properly: Automatically diagnose and fix Windows audio playback problems

If issue persists, please follow the link for detailed instructions: NO AUDIO OUTPUT DEVICE INSTALLED....OR RED CROSS IN BOTTOM RIGHT HAND CORNER ON VOLUME CONTROL

Also if issue persists, please provide me the following information:
