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.

Preferred Solution: Realtek Audio: 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: 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.

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!

Basically the other after i booted up my computer i had no sound at all and on the bottom right hand corner there is a speaker with a X through it saying No Audio Output device is installed. So first i intalled new drivers (windows 7 Comaptible) and still nothing. There is nothing in device manager that needs a driver and "Under the Sound, Video and game controllers" Tab it just has "Unsupported Standard Game Port". I am using the onboard sound card on my motherboard which is a Gigabyte GA-81E. I have only recently upgraded to Windows 7 Home premium for windows XP though the sound was working perfectly intially it was only till one day i booted it up and stoped working. Any ideas?

Any assitance would be greatly appreciated.

This problem started when I accidently allowed a Vista update on my computer. I tried resetting the computer to an earlier date to get the sound back. Resetting the computer destroyed it. I took the computer in to get it reformatted, it works now, but still no audio. I tried updating the drivers, but the system says the drivers are up to date. I tried disabling the audio and rebooting the computer, still no audio. Computer is worthless to me without audio, half the reason I have it is for sound manipulation. Can anyone please help me? Do I have to buy a new sound card? New motherboard? What do I have to do to get sound capability back?

Im pretty sure it is just a driver. Try this. Safe boot (F8) and un-install the driver. On reboot vista should find a driver. see if it works. If not let us know and I will research it for you.

I'm running Vista on a ThinkPad R61i. A few days ago, I started getting messages that the "on screen messaging system" wasn't working, my volume and mute buttons suddenly stopped functioning, and my audio went out completely. The volume control icon has an X beside it, and when I mouse over it, it says "No Audio Output Device is Installed."My audio had been working fine since I got the computer this spring, and I haven't uninstalled anything. Thoughts?

Ok so this is my first time on this site. I'm running out of solutions and I've called two tech support places and still I havnt found a solution for my problem. The issue is rather stupid and I really don't understand why it's not working but here it goes. I don't go on this computer its my mothers and i've been working on it for the past month now. For some reason the Audio Output Device Uninstalled it's self some how and for some reason it's becoming a pain to get it back on.

I've done these things so far.

1. I've went to the device managers, uninstalled the Audio Device Driver ( Realtek High Definition Audio ) I've restarted my PC hoping it would Install the Driver. It starts it but for some reason after a few moments it always seems to fail.

2. I've even tried doing a system restore to the computer, weeks on back to see if maybe that would help and that didn't work either

3. I've called a tech support and they ran me through a thing to where I uninstall the Driver, go to the site ( I went to Acers Support Site and Downloaded the right driver for it ) I ran the download, did the set up. I rebooted my computer and STILL! It didnt work.

I talked to the Support guy again and he told me that was the weirdest thing he's ever seen. So far I still dont know what to do, I tried calling Acer Support but I can't get through so i'm guessing it's only open for so long.

Hi.I'm going to try and keep this post short and not rant on if I can help it..Sound icon (bottom right in task bar) displays 'No Audio Output Device is Installed' with a red cross over it.. Conexant/High Definition Audio Driver can be installed, just not correctly or in other words it fails ..

Iv'e also went into Device Manager. Now in here iv'e tried several things like
1. Uninstalling Intel(R) Display Audio and restarting my computer, it started re-installing but then it says it failed to.

2. Iv'e disabled it and enabled it (Didn't work)

3. I tried updating the driver but it was up to date (Still didn't work)

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?

A:no audio output device installed

Hi what exactly is the problem, is it that you don't physically have a soundcard installed or is it that you are getting an error reporting that you have no sound hardware installed? if it's the latter then there are a couple of options one is that you have no drivers for the soundcard or they are corrupt or not up to date, and the other is that you don't actually have a soundcard installed.

I have been dealing with this for the last week and nothing i try works. I have a KA3 MVP elite group mother board with intergrated sound. An athlon x2 4800, 2g ram. Audio was working fine, opened up my tower, ran some HDD checks in BIOS, now vista reads "no audio output device installed", Tryed update/uninstall/reinstall drivers-no good, checked hardware no problems. Vista doesn't recognize any audio devices tried refreshing and no change. I have been all over multiple forum and tried all kinds of wacky thing with no luck. This is starting to drive me crazy!!!

A:No audio output device is installed


I had this problem a while ago when my computer crashed after attack of trojans... i couldn't figure out how to sort it out... neither could a professional!

The best that i could do was to bring it back to the time that it was working properly using system restore.

Going to the start panel and typing in system restore and finding the date that it was working properly then let it do its stuff.

This shouldnt affect any documents but just incase BACK THEM UP!!

hope this helped

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.

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:

1. Does the computer have external sound card?
2. Did you try to download the drivers from vendor?s website?

Please post the results.

so i just got internet to my computer after almost 2 years of it being out of comission, it still worked and we were able to play games like solitaire and the sims but there was no internet hooked up to it. it installed all kinds of updates and one night i was listening to music via wmp and the next day i went to listen and it said "no audio output device is installed"

i tried updating the device and it said that my driver was up to date.
i also tried uninstalling it and rebooting my computer and that didn't work.
i don't see any error messages in the device manager, i clicked the icon with the little magnifying glass and nothing showed up.

i don't know what else i can do, besides take my computer and throw it into traffic.
i have alot of music on this computer that i listen to on a daily basis and would hate to have to switch it all to a new computer, or even buy a new computer for that matter just because my speakers aren't working.

they're realtek high definition audio btw, that seems like something i should prolly mention.

can someone please try and help me?
thank you.

A:'no audio output device installed' but more

See whether you can find the audio driver for your model PC on the HP website. Else go to the website of your sound device manufacturer. If you don`t know what this is, type msinfo32 into the start/search field and hit Enter. Then expand "Components" and go to "Sound Device". That should tell you the manufacturer.

Since about a month or two ago, I've been experiencing audio issues with this laptop. Sometimes after a reboot the audio icon will have a red 'x' and the "No Audio Output Device is installed" message is displayed when I hover over the icon. I've tried installing the most recent audio drivers via the HP Support Assistant, removed the hardware from Device Manager and have it re-detected. Sometimes this resolves the issue, but more often i just have to keep rebooting until the error message disappears. The Windows Audio Troubleshooter can't identify the problem, and rebooting until the audio works again is becoming tedious :/ OS: Windows 10 Enterprise, Version 1607 (OS build 14393.447)

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?

ok so I just installed a service pack onto my laptop and all of a sudden I have no sound. It says "no audio output device installed". I am not happy about this, i have had nothing but problems using Vista which include having to load the OS discs more than once and these updates are created more and more problems and I this issue needs to be resolved asap because I use this computer for homework and some of that homework includes having to listen to sound bites. What will fix this issue? i have used Microsofts FIX IT thing and tried these how to fit it deals with no success.

Hi, I'm running windows 10 on a W540 with Realtek High Definition Audio and Dolby Digital Plus. Rececenlty I noticed the Dolby Digital Plus utility was not working.  Based on guides from lenovo I uninstalled and reinstalled my audio drivers. Now Dolby Digital Plus is running but I have no audio. The audio icon says no audio output device is installed. Realtek does show up in device manager. Windows troubleshooting says audio services not responding. Restarting them does not seem to fix anything. The only other suggestion I've seen is reinstalling windows 10.
