I have spent the whole day with this C media problem now and I still get nothing. My new Chaintech 9PJL1 motherboard with

the C-Media CMI8738 audio chip is not working properly since I changed my OS from Windows XP SP3 to Windows 7. I tried to update the C media CMI8738 driver through device manager and with windows update,it still gives me no sound. But It used to work perfectly under Windows XP. Does anyone have this problem as mine?
