I'm seeing the same thing with my bt8x8 setup. I've been trying to debug 
the problem, but not getting very far. I've noticed that during playback 
the lastaudiotime variable seems to be screwy (very high, randomish, 
number). This seems to be because the effdsp value is unusually small 
(i.e. < 100) rather than its normal 7 digits.

This is the code that's setting the low effdsp value 

if (frameheader.frametype == 'S')
     if (frameheader.comptype == 'A')
         if (frameheader.timecode > 0 && frameheader.timecode < 5500000)
===>        effdsp = frameheader.timecode;

On the bad recordings, this frameheader.timecode starts at a low number 
(<100) and rises slowly during playback. On the good recording, 
frameheader.timecode starts high (around 3,200,000) and falls during 

Totally out of my depth here, but maybe that'll help someone work out 
what's going on.
