I don't have a new computer, but just upgraded to the vista. I had sound
before and don't now. Any ideas

I have a Sony Vaio VGN-FE45G/W and if I use the sleep mode, the sound is
often lost after coming out of "sleep". So, AVOID using the sleep mode!
Microsoft has published a fix for this KB929685, but when I try and install
it, I get a message that says: "The update does not apply to your system". I
did use the correct version (32 bit) of KB929685:

http://support.microsoft.com/kb/929685/

So I'm not sure why my no audio with Vista problem shouldn't respond to
KB929685?

Anyway, I tried doing this:

Control Panel: System: Device Manager: Sound video and game controllers:
expand and right click on high definition audio device: then uninstall the
driver. Then put the computer to sleep and power up again and the driver is
reinstalled. This worked OK, but then since that time, if I use the sleep
mode again, the sound is sometimes lost again. So I went through the
uninstall procedure again, and went in and out of sleep, and it still didn't
bring the sound back. GRRRR... but after a couple of complete power downs
and reboots, the sound did reappear! So this uninstallation trick doesn't
always work and persistence is needed!

Uninstalling and reinstalling drivers is often the first step in solving
lack of sound (and other) problems, but my post may not work for your
problem.
