Onboard C-Media sound doesn't work on Soyo KT400

[hwyblues]

I recently put together a new box which includes a Soyo KT400 Dragon Ultra Platinum motherboard, which comes with the C-Media CMI 8738 audio chip. I can't get any sound to work. I've uninstalled/reinstalled the drivers/apps for the audio chip a number of times. The most sound I ever get is a split-second piece of the XP startup music after rebooting -- I hear it for a brief moment then it stops. No other system/audio sounds ever work. Running XPsp1a. I ended up disabling the c-media chip and putting in my old Soundblaster Live card and that works fine.

Any ideas what might be wrong with the c-media sound?

If you hear music for a few seconds, it should not be a jumper or bios setting. Are your speakers powered? Not all speakers work on all boards. Do your speakers have a digital plug?
