Comment (by verem):
Replying to [comment:3 lennart]:
> aplay doesn't use poll() on the fds in question. PA makes use of a much
larger set of ALSA API functions than aplay. If something works in aplay
it doesn't mean the driver works completely correctly.
i just tested agains test/pcm.c (http://git.alsa-project.org/?p=alsa-
lib.git;a=blob_plain;f=test/pcm.c;hb=HEAD) in different modes:
./pcm -m write
./pcm -m write_and_poll
./pcm -m async
no problems at all, i hear a tone, CPU load approx 4% on PII266Mhz.
could you post modified test/pcm.c exaclty with same method used in $subj
to check your idea?
