Recovering a vista home Premium 32 bit laptop for a friend, just noticed sound stopped working, so i restored it back a few days to when i though it was working, still no luck, when i open the control panel/sound the device "speakers and dual headphones " is set as default, right click then choose test and is says "failed to play test tone"
the only other device listed is :
SPDIF ( digital out via HP dock)

restored back as far as i could, still no sound...
i found a link for a registry fix, but it didn't apply in this case as the entry wasn't present.

Not sure what happened here or how to get the sound back.

Go to Device Manager...click detail for Sound, Video, Game Controllers. Anything listed there for "Hi-Def Audio", "Audio Contoller" or something similar? Probably not.

Any unknown devices with yellow markings in Device Manager? If so, then try installing the audio drivers for the system, downloadable from the support website of the laptop manufacturer.

i downloaded and reinstalled the audio driver form the manufacturers website as suggested and everything is back to normal. Not sure what caused it, but its fixed.
