[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: ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe There’s also an article around the SP file here: http://h10025.www1.hp.com/ewfrf/wc/genericSoftwareDownloadIndex?softwareitem=ob-47284-1&cc=us&lc=en&dlc=en. 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:
HDAUDIO\FUNC_01&VEN_14F1&DEV_5047&SUBSYS_103C30A5&REV_1000
HDAUDIO\FUNC_01&VEN_14F1&DEV_5047&SUBSYS_103C30A5
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 IÂ 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)Â , 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.
