Vista SP1 – still no audio after resume from sleep

February 12, 2008 10:45 am

[Update 2012-03-03: Since there still seems to be no real solution at the driver level (after 4 years), I’ve written a little app, that at least puts a band-aid on the problem. Check it out. Now you can reset the device without having to go to Device Manager and disabling/re-enabling the device.]

[Update 2 2008-11-29: I think I may have found a package that solves my particular problem. I’ve put the computer to sleep several times now, and each time sound came back properly after waking it up again. The thing that seems to have done it is something called a UAA Bus driver. I got it directly from the HP FTP site here: There’s also an article around the SP file here: I’m not sure this will help your situation, but it helped mine (so far, keeping my fingers crossed, maybe I’ll run into other issues with it.) The article says it’s for XP, but it seems to have worked on Vista SP1 as well.]

[Update 2008-11-29: I’ve looked around a bit more. The chipset used in the HP laptop is of the “Waikiki” Conexant HD audio variety, according to this forum post. Apparently there is an online petition, asking for HP  to release an appropriate driver, since some of the notebooks that use this chipset were marketed as “Vista Capable”. The “Venice” chipset variant, apparently, is covered by updated drivers.]

[Update 2008-07-24: This is now one of the most popular posts on my blog. Seems to me that a lot of people are having issues like this. Unfortunately there only seems to be a solution for Sony systems; look through the comments to see it .]

I have a laptop that has an issue with properly restarting the sound subsystem after Vista resumes from sleep. Microsoft brought out a hotfix about 6 months ago that supposedly fixed issues like this. On my system, the problem persists, even after installing Service Pack 1! I let the computer go to sleep, and when I wake it up again, there’s no sound. The sound device is listed in Device Manager as “High Definition Audio Device” and has the following Hardware IDs:


I’ve tried just restarting the sound services (as admin: net stop “Windows Audio”, net stop “Windows Audio Endpoint Builder”, net start “Windows Audio Endpoint Builder”, net start “Windows Audio”), but that doesn’t work. Restarting the computer works, obviously, but is too slow to be a proper solution.

One thing I can to do to get sound back without restarting is remove the “High Definition Audio Device” from Device Manager and then Scan for Harware Changes. But it’s still annoying to have to do this. Since there’s no crash involved (no Windows Error Reporting possible) and no “yellow bangs” in Device Manager, I’m not sure how I would report this to Microsoft. They probably wouldn’t do anything about it anyway. They’d say it’s a driver issue. Talk to the driver vendor. Nice idea. Trouble is the laptop is older (it scores a 3.2 Windows Experience Index, not half bad) , and the vendor probably won’t bring out Vista drivers for it. So it looks like I’m stuck with a broken package.

Maybe a kind soul (at Microsoft?) will read this at some point and get in touch to help me troubleshoot the issue.

Oh well. Feels good to get it off my chest, though.

Did you try applying this patch?

I found it by doing a google search with query “vista no sound after sleep”.

Hope that helps!

GeekTieGuy wrote a comment on March 14, 2008

Umm, yes, that’s the hotfix I linked to way at the top of my post. I believe that SP1 supersedes or includes it. It’s still installed on the system I have the problem with, anyway, even after installing SP1.

Any other suggestions are very welcome!

I guess one other detail about the problem is that the computer has more than one user account on it, and sometimes it gets put in hibernation with both users logged on.

Eric Yun wrote a comment on April 2, 2008

KB937077 is in SP1. Are there many devices connected to your laptop? Will the problem go away if you remove those devices?

GeekTieGuy wrote a comment on April 3, 2008

I only have one other device that I connect from time to time, and that’s a Wacom digitizer tablet. (Incidentally, when this is plugged in, the laptop won’t wake up from sleep properly. It turns back on, but then doesn’t proceed past whatever the BIOS wants to do before handing control back to Vista.)

I tried various resume from sleep scenarios to see exactly when the problem happens. My conclusion so far is that as long as the laptop doesn’t completely power off while in sleep mode, sound comes back properly.

I specifically made it hibernate and then unplugged the power cord and removed the battery to force it completely “off” while in sleep mode. When it resumed from sleep (hibernate, to be more precise), it had no sound.

Just to echo that I have this very annoying problem too, on Toshiba Satellite running Vista SP1. There still doesn’t seem to be a definite solution but it MAY be helped by an updated sound driver, since I had a similar issue with an old ATI video driver too, not working after resume. However, my sound drivers ARE up to date in my case…

GeekTieGuy wrote a comment on May 7, 2008

I’ve looked for updated drivers, but so far no luck. And I’m kind of tired of having to keep looking. Maybe Windows Update will bring me one some fine day.

I have the same prolem with satellite p105-s6147

Eddie wrote a comment on May 24, 2008

I have the same problem on a new Sony Vaio VGN CR220E notebook (the red pretty one). I called Sony and they acted as if they’d never heard of the problem. The best they’ll do is send me a box and have me send it back and wait 7-10 business days (2 weeks!!!) and they’ll just reinstall everything. And *maybe* that will work. Wow. Lose 2 weeks of business and *maybe* starting over will work.

I too had hoped that Service Pack 1 would resolve it, but it hasn’t. Here’s what has worked so far, thanks to a suggestion from another post:

After the problem occurs (usually when I log back in after a long sleep), if the sound doesn’t work, I purposefully go into Hibernate (have to wait 2-3 minutes to make sure the battery indicator stops, to make sure it’s completely hibernated). Then I power back on to resume. Voila! The sound reappears.

It may not make sense, but it’s 3x quicker than shutting all the way down, then restarting all my apps.

Same here for a Toshiba Satellite A-100 Notebook , tried hell lots of drivers for the audio card , its the same.

drr wrote a comment on June 1, 2008

Same problem on a VGNCR305, or even worse. There’s no audio after booting vista sp1 normally (sometimes). Already installed Bios update and Realtek audio driver update. It worked for a while since before updating windows only played initialization sound but then…
M$ and Sony just keep foolishing us.

drr wrote a comment on June 1, 2008

*Correction: “…before updating drivers…”

It seems that disable/enable audio device works.

Guy wrote a comment on June 14, 2008

Same problem on Toshiba Satellite 100-106, only it appeared for the first time after installing SP-1…
any solution yet?

Alex wrote a comment on June 23, 2008

I have the same problem with VAIO PCG-5J1P. I have windows vista SP1 installed and the driver version for Realteck High Definition Audio is When starting up the system I have sound, but if a wait more than let say 30 secs the audio is gone. I have to hybernate and de-hybernate and then the sound comes back. I’ve also found that if I start any playback program (i.e. winamp) immediately after the system starts up, the sound is never gone. But if the song playback ends and there is no new sound after some seconds, the sound is gone again. So the solution I have in the meantime is never to shut down winamp! I think I did not have this problem before updating to SP1
Please if anyone knows a solution, please post it here thanks

Alex wrote a comment on June 23, 2008

Well like ussually happen, it’s just about posting and you’ll find the solution a minutes later. For Sony users, sony has released a BIOS update in his website that solves this issue. The problem comes with the instalation of windows vista SP1 and this BIOS updates solves

I had the same problem on my Sony Vaio VGN-CR22G (Black) after I installed Vista SP1. I had no sound from bootup or when trying to play mp3’s. i checked my earphone port, also not working, tried to play an mp3 file on a Live Linux boot Cd, that worked. So it could only be a driver issue.

I downloaded the Vista sound drivers from Sony’s Asian website, don’t know if it’s any different than the US/Euro version, but it WORKED for me. Now I’ve got my sound back again.

Give this a try:

Enter a model closest to yours and search for audio.

MingS wrote a comment on June 28, 2008

Thanks NZHelper for your comments. I”m also from NZ and with the same Sony VAIO laptop and same problem! No sound in Vista after hibernate. Anyway, used your suggestion and all is now great – thank you very much. Found I had to search for model number in downloads link (as above) then in the top blue search box use the string [model #] +vista +audio.

Sorry this is no help to people with other brands of laptop. Microsoft are not doing anyone any favours by being helpful, that’s for sure.

Gareth wrote a comment on June 28, 2008

I have the same issue. For some reason when I tried some months back I couldn’t install the hotfix, but randomly found a neat trick to easily resolve it at around the same time so didn’t investigate further.

1. Download Skype.
2. Set up a contact, anyone to call. Not tried it as I use Skype and have a few contacts, but you might be able to set up a fake one.
3. Dial someone who’s offline.
4. For some bizarre reason, the dialling tone for skype resets whatever the issue is with the drivers / sound / whatever, and restores fully functional sound.
5. I think this is only an issue with machines with HD sound, but I may be wrong?

Paul Higginbottom wrote a comment on July 7, 2008

Same issue here, no sound after resuming from sleep on a brand new Dell XPS 420. Very frustrating. Dell says it’s a “vista problem”.

I will post back if I find a solution.

Joel Dankwa wrote a comment on July 15, 2008

I have the same issue on my Sony Vaio CR190. It’s the biggest pain. At least nothing is wrong with the hard drive of my actual vaio and this is simply the fault of the OS. I’ve been looking around, and there have been no signs of a fix as of late.

Jamel L. Raines wrote a comment on July 17, 2008

Same problem I have with Sony VAIO VGN-CR190 will give the BIOS update from sony a try.

Jamel L. Raines wrote a comment on July 17, 2008

Also the Workaround given by drr works great!

Christos wrote a comment on July 24, 2008

The thing is that faults like this shouldn’t exist. The KB mentioned are crappy anyway, they cause nothing but trouble.
Anyway, we all should go get a GN/Linux distro and have this crap only for games and photoshop! :p

Uber Schnoz wrote a comment on September 15, 2008

I have a Gateway T-1628 laptop and am having a very similar problem. The difference being that I get squelching and squealing noises after coming out of sleep mode. I think this problem is related to the HD sound cards. The problem didn’t start for me until I installed the 64-bit version of Vista Ultimate. I’m going to try the work-arounds suggested here and will post back if there offer any sort of relief.

Seager wrote a comment on September 17, 2008

I have had the similar problems in the past with my Toshiba laptop and i have found that disabling the sound driver works in device manager, its a bit of a hassle, but its ok when you don’t really want to hibernate your computer.

Hopefully this will work for others too.

Gilles wrote a comment on September 23, 2008

I’ve the same issue, but i lose sound when i play, or when i watch a movie… not only after sleep or hibernate…

I think I’ll go back to XP ^^

Amanda wrote a comment on September 23, 2008

I was having the same trouble with my Dell. The first time it happened, I called tech support, and they had me reload my entire system to factory settings, and said it was the updates corrupting a file. Then it just happened again (my automatic updates are turned off), and I figured out it was from sleep mode. After reading here that somebody just put it into hibernate and took it back out again, that worked, my sound came right back! So try that first as a quick easy fix. I’m disabling hibernate from now on!

chris wrote a comment on November 28, 2008

I encountered this problem several times already and it seems that there’s no solution to it as of yet. I am already running vista SP1 and even tried installing the mentioned vista “patch” suggested above, but according to the installer, the update wasn’t for my system, when I clearly downloaded the correct installer for my Vista’s version.

I’m using Compaq presario B1200, 3Gig RAM, dual-core 2.0GHz

Dan wrote a comment on December 10, 2008

This is a problem across the board with Vista I have a Dell XPS 420 and have the same problem as everyone above. There is no current fix for this as far as I can tell other then going back to XP.

Harris wrote a comment on December 12, 2008

I found a quicker way than restarting the computer. What I did was disable the High Definition Audio under “Playback Devices” then re-enable it. Hope that helps.

STILL NO AUDIO on Sony Vaio VGN-SR16GN running Vista Business!
My audio has been gone for about a month, and i finally have had time to try and trouble shoot.
I have tried all the fixes mentioned in the above posts and more as detailed below and I have no audio through speakers or headphone jack.
The following are a some of the fixes i have attempted with no luck:
– Installed latest Audio driver available on
– Installed latest driver from
– Installed default windows audio driver
– Disabled / Enabled sound device
– Skype fix attempt to initialise audio device
– Updated all Sony Vaio software through Vaio Update
– Updated all Windows Update software
– Searched archives online everywhere including Sony and Microsoft

All the software thinks the drivers and device are functioning correctly. Microphone works.
But there is still no audio output through speakers or headphone jack.

I suppose its off to Sony I go! They’ll likely reformat and start over! What a hassle!

Any other suggestions welcome please?

Have same problem with my Sony VGN-CR220E laptop: sometimes (not every time) after long sleep there is no sound coming out although all the software (windows, skype, winamp) shows sound is fine (that is sound levels are changing while playing back music).
Simply going back to sleep and waking up right away helps me to get the sound back.

Raul wrote a comment on February 8, 2009

Sony cr 220e un install your HP device & reinstall through sony downloads it worked for me now 3 weeks no more sound problems

Craig wrote a comment on March 21, 2009

The quickest “bandaid” I’ve come up with is to open device manager and “Scan for hardware changes” found with right click after a sleep or hybernate waking. Hope they get a fix soon !!

Squid wrote a comment on April 15, 2009

I built my PC and know everything is up to date with correct drivers, however after sleep I also get no sound. I find that logging off and back into Windows sorts this. Annoying as after a sleep I will miss calls as I can’t hear any sound, the odd thing is that the graphic equaliser shows sound is being processed? PC running VISTA Home Premium, ATI Radeon 8070HD. Dual Core 3Ghz Intel. I oringonally suspected the HDMI handshaking procedure as this is a relatively new technology but after reading this, it seems like a joint issue between VISTA and the sound drivers. I may try installing UBUNTU or Linux Mint and see if that is any better.

I installed Vista SP2 RTM and it seems that this problem does persist. It’s really annoying, but I will try out your trick, perhaps it works.

This problem persists with my dv8000t on Windows 7 RTM. Trying the UUA trick….

Tom Carruthers wrote a comment on April 14, 2011

I had this problem and found a handy solution.

This works for me (Vista SP2). Control Panel > Device Manager > Sound, video and game controllers. Right click on your sound card (e.g. ‘SoundMAX Integrated Digital HD Audio’) and select ‘Disable’. Then right click on the sound card again and ‘Enable’. Done.

Not elegant but you don’t have to restart your computer each time!

Hope this helps someone!

Ricardo Morales wrote a comment on October 22, 2011

Tom Carruthers: Your suggestion was the only one that has worked with my VAIO VNG-CR220E with Windows Vista (SP2). As you said perhaps it is not the most elegant but it really works.

What I did as extra was to add a System shortcut in my desktop with some keywords to follow when I have the problem again. For example, “System – Dev Manager- Sound – Realtek – Disable – Enable” (Realtek is my sound card).

Thank you very much for all the suggestions..!!

I had a similar problem. My Xonar sound card wasnt even being detected when returning from S3 sleep. Hibernation worked tough.
The solution was updating the motherboard BIOS to the latest version.
