Vista SP1 - still no audio after resume from sleep

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