Just a test, but try hacking the audio output code to use much larger 
audio buffers.  Make it try to setup as large as possible (just change 
the relevant lines to be as large as possible, under Alsa it should then 
pick reasonable working values that fit your requested values.

At the moment you might be having the PC context switch more often than 
once a frame, which eats up enough time that you miss your next audio 
priming stage.  Try to get large enough buffers for more than one frames 
worth of video. (try 16 buffers of 8096 samples and see what your card 
actually gives you...)

Good luck
