Alexandre Ratchov 436f0dbfff Fix builds with no DEBUG defined. 2019-07-28 11:26:51 +02:00
Alexandre Ratchov cbdd29c403 alsa: use (blksz - round) as start threshold. 
The threshold making poll() return POLLOUT is one block (according to
alsa library sources). If a poll-based program writes blksz - 1
samples, playback never starts but poll won't return POLLOUT either.
In turn the program deadlocks. The problem could be observed in the
sio_alsa_xrun() routine.

Alexandre Ratchov 0e0511c762 for alsa, POLL{IN,OUT} events mean that a block can be read or 
written (not a byte as unix files expect). Use "tickets" counters that
are reset to hdl->par.round on each POLL{IN,OUT} event. Limit read()
and write() to one block to ensure poll is always called at block
boundaries.
