Subject: [linux-audio-dev] async latency problems?

maybe i'm missing something somewhere, but is there a reason why i can't
seem to get audio processing via async handlers to work reliably?
i'm using andrew morton's kernel patch for 2.4.18.....and i can crank the
latency test program all the way down to 64 frames with no trouble. but
when i try to do things with async handlers, i get underruns from typing
in xterms or things simpler than that
i can rewrite my code to work without callbacks without much effort..but
i'm confused as to why this might happen, considering that blocking
through snd_pcm_wait() shouldn't be that much different as far as process
wakeup time
