Out of curiosity, are you using dmix or direct hardware? It looks 
conspicuously like a problem with the total number of bytes written to the 
device through ALSA causing an overflow, in which case it doesn't matter what, 
if anything, is actually played with OpenAL. It keeps sending samples to the 
device anyway.

Just to be sure, there are no messages printed to the console by OpenAL when 
the problem occurs?
