Right Jaroslav,
that means i would modify intel8x0.c to include a
call to
snd_pcm_hw_params_get_period_size() or
snd_pcm_hw_params_get_period_time() in the appropriate
place. Write the values returned say to a text file.
Recompile the ALsa driver and re-insert it into the
kernel.Start my application and check contents of text
file.
Am I right in saying this?
Thanks in advance,
Brian.
