I've noticed that programs using pcaudiolib with ALSA sometimes lock up
during the call to audio_object_drain.
From what I can tell, this is due to snd_pcm_drain being called when
the pcm handle is in a state other than SND_PCM_STATE_RUNNING or
SND_PCM_STATE_PREPARED.
This may be a bug in the alsa library libasound, rather than pcaudiolib itself.
