Realtek Audio: No Audio Output Device is Installed

Q: Realtek Audio: No Audio Output Device is Installed


Im having the dreadful "No Audio Output Device is Installed" problem on my realtek audio.

It worked some months ago, but im in no position to do a roll back. Im sure the hardware is just fine, it works with Ubuntu.

The computer is a Dell Vostro 430.
My OS is win7 64bit.

I tried the newest Realtek driver suite, the recommended dell-drivers and some basic windows-drivers. Nothing makes the "No Audio Output Device is Installed" go away.

Any help is welcome.
Ive attached my sound-related reg. I believe my realtek device is 0001.

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: Realtek Audio: No Audio Output Device is Installed

The Dell driver is required, non Dell drivers will either not work or not work correctly.

First thing, is the Integrated Audio enabled in the BIOS? (F2 at boot up to enter Setup).

Second, on Dell's (and many others) if the motherboard chipset drivers were not installed, the sound device will not work. In this model there are Intel motherboard chipset drivers. Try installing them and then the Dell sound driver. Dell Drivers

I've spent countless hours trying to fix this. It started out with me wanting to enable the "stereo mix" option and so following a youtube video I proceeded to updating the driver using device manager > update driver and after restarting, I received this error.

I then downloaded the newest driver of the manufacturer website (realtek hd audio) realtek.com and installed it. Mind you, the stereo mix option did in fact show up, although I couldn't make use of any audio since I was getting the "no audio output device is installed" error.

All this time, I can still see the mic/line-in inputs, and headphone/speaker outputs in the sounds (control panel). I have tried uninstalling, reinstalling, and using the roll-back option for drivers. Although from control panel, I managed to uninstall the sound card software for realtek. Between all of this, after any sort of install or uninstall I also restarted my computer.

I downloaded the drivers from the HP site (PC manufacturer for my comp) and the Realtek site (sound card creator) and all of them are giving me the same results.

Furthermore, I even tried the System Restore and it wouldn't work complaining about an anti-virus when all of mine are already disabled. I checked what the System Restore would affect too and nothing for my driver was in there as far as I know.

I'm really not sure what my options are now, and it's sucks not having any sound.

Please help me out! Thanks!

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).

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 @JD_gin?,Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP Pavilion x2 Notebook and issues with sound drivers not installed correctly. In the Device Manager, right-click on Double-click on Sound, video, and game controllers and select all that are listed and uninstall the Driver Software. Here is the download to the Realtek High-Definition (HD) Audio Driversp69248.exe. You could  try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows.  Please restart the Notebook twice to make sure all update have been completed! You could also try in the Device Manager, click the arrow next to Display Adaptors to expand that categoryRight-click on Graphics and select Update Driver Software if more than 1 Graphics adapter do 1 at a time.Choose the option to Search Automatically for Updated Driver Software.The Notebook should find and automatically install the updated driverAfter the installation is complete, restart your Notebook.Please let me know how this goes.You can say thanks for trying to help by clicking the Thumbs Up below!.Thanks.

Hello all I have Win 7 32-bit on my gateway mx6437 and am having the same problem that several people are having here - no sound. I downloaded the latest Realtek AC '97 drivers from the Realtek website. I checked to see if this card was compatible with Win 7 32-bit from the compatability website. Right now the drivers are "installed" but Win 7 says its unsuccessfully installed.

I have an AMD Turion 64 card. Please help I've been researching this issue for the past 2 weeks without success.

first I already wanna thank everybody who replies to this and try to help me. Yesterday morning I tried to download a sound driver that would make the Stereo Mix option available. It was not from the original website of Realtek or HP. It was from here: http://driveragent.com/c/archive/196a161c/Realtek-High-Definition-audio#summary. After I finished the installation and restarted my PC there was a red cross next to the sound icon and when I tried to open volumemixer it said 'No audio output device installed'. I tried to uninstall it with system restore. Than I also tried to install the latest sound drivers from the Realtek and HP site but both didn't work. Also I saw on another topic that maybe some services were stopped but that wasn't. Now I really don't know what to do. Hope someone can help me.

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

Hello, and thanks in advance for your time!Earlier this afternoon, I noticed that the sound on my Thinkpad W510 was no longer working. I hadn't really done anything of note with my computer- just updated Adobe Reader to v9.2, that I can think of. When I checked the notification area, I saw this:However, when I right click and click "Playback Devices", I get the following: I immediately checked Device Manager, and found that everything appeared to be fine:I tried uninstalled and reinstalling the Conexant and NVIDIA drivers, as well as updating BIOS. Nothing seems to help, When try to use the mute/volume buttons on the keyboard, the speaker mute button lights up when pressed, but the microphone mute and volume +/- buttons don't appear to do anything. I've also tried plugging in headphones, and that does not make any difference. When I boot from an Ubuntu CD, however, sound works fine, so I don't think that it's a hardware issue.Anything that you folks could do to point in the right direction would be greatly appreciated. Thanks!

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.

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.

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've managed to find the way to boot Windows 8 without requiring valid digital signatures (error code 52).  Seems the HP IDT High Definition Audio CODEC is not in compliance with Microsoft... interesting in itself, but until there is a new updated driver available this is what I have to do every time I boot the computer to have my sound back... a bit of a pain but when lWindows is loaded follow these steps. * Go to PC Settings - General - Scroll down to Advanced Start Up - Troubleshoot - Advanced Options - Start Up Settings - on the next screen use 7 or F7 to Disable Device Signature Enforcement Love having my sound back, just a shame HP couldn't help.  Hope this helps some of you experiencing the same problem as me.

chickenbad" No audio Output Device is installed"
Hello Kevin. When you open the Device Manager and expand the "Sound, video & game controllers" category, do you see "High Definition Audio Device"?

If not, then Windows is not detecting the audio hardware on the motherboard. One reason that can happen is that the audio is turned off in the BIOS. Most Dell BIOS do not have a setting for audio, but a few do. I don't have a list of which models have audio in the BIOS, so check yours. If you don't find a setting for audio, then audio is ON by default.
Another reason for Windows not detecting the audio hardware is that the hardware might have failed. Test the audio hardware by running the audio test in Dell 32-bit Diagnostics. The Dell 32-bit Diagnostic was on a hidden partition of the original hard drive that shipped with the laptop. If you no longer have the original hard drive, or if the partition has been wiped from the hard drive, download the Dell 32-bit Diagnostic files (CW1394A0) and run the diagnostic from a flash drive or cd. Expand the "Instructions" category and read "Custom Instructions for CW1394A0.exe".
When you get the diagnostic installed on a flash drive or cd, see these instructions for running the audio tests.
An alternative to using Dell 32-bit Diagnostics is to perform a system recovery (revert the laptop to the original factory configuration). If the audio fails the audio tests, or if it does not w... Read more

Tried Installing all the latest Drivers from Samsung website. Nothing as of now has worked.
Tried installing realtek from both samsung and realtek website. Driver installs but visible only in add or remove programmes. Not visible anywhere else in the control panel(hardware and sound).
Used Driver Pack online. no improvement.

A:No audio Output Device is installed

Read other 15 answers

Long time ago, I play with upgrading HDD to SSD, GRUB and some other stuff and I failed and messed my computer up. Now my desktop is still using HDD and does not produce any sound. I tried to fix this problem by Googling "No Audio output device is installed" but I couldn't get it to work. It's been a long time for my desktop to have no sound and now I have decided to come to this forum and seek help to solve this problem.

Please help me fix this issue.
If there are any information that I should provide, please inform me.
Thanks in advanced.

As a note, I don't really care about upgrading to SSD anymore, but I want my computer to have sound.

A:No Audio Output Device is installed

Upgrading HDD to SSD, this means you changed the harddrive ? In this case you should do a clean install to the new Harddriver(SSD).
If you did put your HDD back, everything should do as before ?
GRUB sounds more Linux specific, did you try to install Linux ?
Maybe I read it all wrong I don't know but try to check on DEVICE MANAGER if you have installed the driver for your Sound device first.

When I go to problem device I get this

Your description of the hardware in your post sounds like a device manager properties dialog. Try to update driver software through device manager (right click my computer >> properties >> device manager (navigation dependent on OS)).If you right click the device in the device manager and select "update driver software", that could fix it. You can also try uninstalling, then re-installing the device through the device manager.

Oh, I just noticed the name of that text file from dxdiag so you probably weren't in the device manager. Go to the device manager and try what I posted above.

I have tried updating,reinstalling, downloading new drivers....nothing works to get sound on my laptop. At first I could just update the driver, restart and get sound for awhile....then have to do it all over again. Now I'm just confused...I need a new driver that will keep working. (ADS Instant HDTV pci). Can someone walk me through this?

A:No Audio Output Device Installed

If the hardware is disappearing from Device Manager and Windows is showing "no device installed", then most likely the hardware is failing/faulty. Windows can only install drivers for hardware that is detected. If the hardware is not detected, drivers can't/won't install and are unnecessary.

I have a Gateway MX6426 laptop. I upgraded, (new install), from W$ xp to W$ Vista. I mouse over the speaker icon, which has an X through it, it states, "no audio output device is installed". I'm certain that this is a driver issue. When I look in the device manager, I have no directory listing for "sound, video and game controllers". In listing labeled, "other devices", the Mass Storage Controller, and the Multimedia Audio Controller are listed with no driver, (a yellow exclamation point).
I have looked for updated drivers, and found out about the missing sound folder while I was searching.
Also, I went into regedit, on my desktop, and exported the sound files from there, (same OS), copied to thumb, installed on gateway, hoping to create the directory. NOPE
I dont know what else to do, HELPMEPLEEZ.

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'm running vista on my hp g6000 notebook & this past month I've been haunted with the dreaded red x over my volume with the "no audio output device is installed". Now when I say I've tried all the easy solutions I really mean it eg. device manager where neither my sound or modem where the Conexant & HD audio are supposed to be are there, recovery manager with the reinstall that says it is complete that does nothing, services where I have reset the windows audio & restarted to no avail. All the above so called solutions have given me the odd faint hope but only last for a minute maybe two before it would go again. I have un installed the audio drivers when I got it back for a minute & downloaded the drivers from hp's site to no avail also. I have a friend who would be more computer literate than me who tried & failed & he advised me to bite the bullet & restore the factory settings which I did, after a day of windows updates it came back & lasted for a day & gone again, right back where I started. I really need some help here cause it is affecting my college work not having the audio. Sorry for the long post but I'm in dire straights here. Any new ideas or help would be appreciated so much. Thanks for reading "if you did".

A:No Audio Output Device Installed

This is beginning to sound like a hardware problem with your integrated sound on your motherboard. Does you lab top have enough room for the vents to dissipate the heat, do you keep your lab top elevated if the vents don't get enough room to vent the heat. There are several heat monitoring programs that I recently found out about called Speed Fan, Real Temp ,and CPUcool. CPUcool being the easiest to use. Install a heat monitoring program. Try letting the computer sit for a while, install driver if it works, note the temperatures. If it stops working during use, note the temperatures if they have changed drastically.

If it is the integrated sound, a cheaper solution might be a sound card. I don't have much experience with lab tops, I don't know if there are PCI fans or cooler fans for lab tops or not.

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.

Hello everyone!
Three days ago I lost the audio on my laptop. I went to device manager and the driver (RealTek HD audio driver) was gone from the list. I reinstalled it but an exclamation mark appeared in front of it with a code 10 error message after installation and obviously no sound. I've tried updating the driver but the same message tells me that the version I have installed is the updated one. I removed it and went to my manufacturer's site to download a compatible driver (found RealTek AC'97_6305 audio driver) but Windows won't let me install it (it can't verify the software's signature or something). I've also tried system restore but no use. I've installed the original driver again using device manager/add legacy software, disable/enable...nothing. Also I get an exclamation mark and a code 10 error on other 2 drivers in network adapters: Microsoft ISATAP and Microsoft Tun Miniport. I've also tried a Microsoft Fix It tool to get the problem solved but to no avail. Also I've moved recently and left the recovery and instalation CDs behind.
I'm at the end of my wits...please someone help me, I don't know that much about computers and I'm lost

Here's the information for my laptop:

Please guys, anyone know how to solve my problem?

Well after reading quite lots of threads related to "no audio output device is installed" and trying different things and suggestions I am stuck with this problem. The above message is shown under Vista and Win7. So I get this message in Vista and Win7. I have an acer aspire 9420 and the sound only works for a couple of minutes (no matter what the operating system is - I tried Win7, Vista, XPSP2 and XPSP3 and always installed the latest driver from the manufacturer site. I also downloaded and installed the latest bios version for this laptop.) And still no sound. I dismatled the laptop 4 times to look at the motherboard and see if anything is OK. There are no bad caps, or burnt or anything. I realized that after hardware reset the sound comes but only for 2-3 minutes at most. Then the sound is cut out and after reboot the Realtek High definition audio disapeears from device manager. My question is: if the hardware is faulty is it possible to work after harware reset for a few minutes? I also tried installing Backtrack5 and still the same. So it's obviously not an operating sistem issue, nor a bios one and not a driver either. I tried different versions of driver. Anyone could help me out?

A:No audio output device is installed

Is this a New Acer, or have you had it for a while.
Many Acer's are not capable of being over-driven. They will become hot and sometimes fail when over-driven at high volume
If it is still under warranty, get it replaced or repaired, and hope you have not voided the warranty by doing your own internal examinations.
If out of warranty, it is possible you may need to replace the system board.
Now might be the time to have an experienced Acer tech take a gander at the innards.

I downloaded and installed the intel chipset driver and then the RealTek driver from manufacturer website but that didn?t solve the problem.

If I buy a sound card from a computer store, perhaps I will also get CD for driver installation with it. If I put sound card in my system and install driver, will the sound function start working. thanks for the help

Sound is possibly disabled in the BIOS.
enter BIOS and check under advanced chipset features
