Microsoft's Engineers are in the gravy. They do a runner. We, the customers, are trying to solve MS's problems by ourselves. I think MS should pay us for our efforts.

Is there any solution specific to Windows 7? I have the same problem as of Irchurch and the solution suggested by Azam didn't work. I am using Dell Latitude E6400 with Win-7 (32 bit). thanks,

My sound only shuts off when after I wake my PC from sleep, and this has happened ever since I installed Windows 7 64 bit on my self built PC. A reboot always fixes the problem. I had XP 32 bit on here first. I've looked around for AGES trying to fix this, and it's really ____ me off now. I can usually solve anything myself, but this one is busting my bawlz. Seriously, I'm thinking about reformatting my entire computer (again...), do you think that would solve it? I am really tired of going through all this troubleshooting ____, I've tried it all and no avail. Reformatting would save me a lot of trouble, even though I have like 60 or 70 gigs of stuff I'd have to move 4gb at a time to my other PC.
