My experience is that ffmpeg video/audio sync is never good - the code takes no care about sync. mp1e gives much more consistent results. But that said, audio sync doesn't seem to be as good off btaudio as off my SB PCI 5.1, even with mp1e. For me it gradually drifts off - perhaps .5sec over 30 mins. I was going to try to find the reason this weekend. For you I'd suggest testing with a different capture program before concluding that the fault is btaudio's. Steve
