I'll work on it.
I noticed that sometimes there are still noticeable intervals. But if I run
some OSS programs first like
DSOUND works very well then.
After some more investigation, I found that snd_pcm_mmap_commit copys the
data as snd_pcm_areas_copy in the origin callback. My patch only decreases
the times that the data are copied. I can't figure out why it works after
run OSS programs though.
