If that's so then your problem must, by definition, be in the playback 
parameters in that frontend.

I would go through everything there with a fine tooth comb to see what could be 
causing the problem. It may be something as simple as video sync methods or 
making sure you have real-time interrupts (or whatever it's called these days).

Don't assume it is the audio at fault. Perhpas the audio is good and the video 
is at fault.
