Just wanted to add that my XRUN detection is rather messed up right now,
and I've already locked up my machine once (stuck in loop with
SCHED_FIFO @:(), so you probably want to run it as non root. Not sure
whats wrong with the way I'm detecting XRUNS, but if I just do a
snd_pcm_prepare, the output stream starts returning
"SND_PCM_STATE_PREPARE" until I restart it. I'll have to look into it
more, but if you have any ideas, please let me know.
