I must test it because after changes it doesn't shows an error.

BTW another case:

if avail = snd_pcm_available() > alsa.buffer_size then I think
that frames_to_forward = avail - alsa.buffer_size

now I do err = snd_pcm_forward(pcm, frames_to_forward)
and returned err is equal to avail

Why?
What is the correct value of frames to forward in emulated OSS buffer:
frames_to_forward or returned err value?
avail % alsa.buffer_size == (avail - alsa.buffer_size) % alsa.buffer_size
in this case which means the same ofs in ALSA ring buffer.
But OSS ring buffer size is not equal to ALSA ring buffer size
so only one value is proper for OSS appl_ptr increasing.
IMHO frames_to_forward but maybe I am wrong.
