------- Comment #17 from Wim Taymans  2009-05-01 07:58 UTC -------
to Comment #16: the software ringbuffer must at least be as big as the hardware
buffer, this is a hard requirement. We currently query the hardware buffer and
set the ringbuffer to that size + 1 period.

A better solution would be to keep the hardware read pointer and our write
pointer within a reasonable distance regardless of hw write() behaves and
blocks. The sunaudio driver has something like that. The thing is that all
alternatives to write() have historically been very flaky on many alsa
implementations. What we really want to use is plain mmap (like pulseaudio) and
fix all the alsa driver out there that would fail.
