I fear the repeat call to snd_pcm_wait() when draining is active would end up in 100% CPU load as long as draining is not done because snd_pcm_wait() would immediate return due to the fact that avail > min_avail at the end of draining. I have not tested it but I could also not find a line which would ignore the avail > min_avail short circuit of snd_pcm_wait().
