An individual has a PC that the sound does not work. If
the sound card is removed from Device Manager, the system
sees the card and reinstalls...no problem there. What
makes this freaky is that even though the sound card is
detected and shows up as working normally in Device
Manager, the default device options (Control Panel,
Sounds and Audio, Audio Tab) are greyed out. There is no
way for me change it.

Soooo...where is the registry key(s) that I need to fix.
This has to be something fairly simple...I just can't
find it.


Thanks!
