I took out my card for a while, and ran the onboard soundcard. Then when I put it back again I lost hardware directsound and EAX in GTA:VC. I have tried reinstalling both GTA and KXdrivers. Dsound seems to work in other games but I don't know how to check. In GTA, the music and other sound works, but the motor sound, brake sound and sword swing sounds etc. are mute. I have DS acceleration enables full in dxdiag. What's wrong?
