I have a MHDT Constantine DAC, which uses some sort of C-Media chip for USB. When I use the current Foobar and the WASAPI plug-in, I get lots of distortion and noise when music is played. When I switch to Kernal Streaming everything is fine. I'm not sure that much is to be gained from WASAPI, but I've been reading a lot about it and I wanted to hear it for myself.

Any suggestions? I've played with buffer size, bits, etc., but nothing stops the noise.
