Hi, I followed your suggestions, the result I got was still jittery sound when I was not using DMIX. I'm sure my sound card can be used for VoIP because when I had Windows I used Yahoo voice to make calls with acceptable sound quality. Do you have any further thoughts about this problem because surely if I can use Windows to call people I can also use Linux!
