I come home from work today to find myself with no sound. After a bit of investigation windows is reading the sound driver as not installed. I've attempted two time to re-install it from the CD and even downloaded the latest drivers from realtec. Every time I install, reboot, and up pops the little balloon "Unknown device CIF Single Chip" I've check the BIOS settings as this is on board sound and it is enabled. Any help is appreciated.
