Yes. So does snd_pcm_mmap_commit().
There is no extra buffer for these functions;
snd_pcm_write/read* copy
the data to/from the same hardware buffer that would be used by the mmap
functions.
snd_pcm_write() and snd_pcm_read(), IIRC, allow reads&writes of chunks
of data that are not period-sized. do you have an alternate explanation for louis'
timing observations?
Apparently a different algorithm.
Louis, can we see your program?
