[LAU] ALSA parameters

[M-.-n]

Hi guys,

I'm trying to get my audio driver working with ALSA but there's the issue of
defining the buffer size and period that I can't seem to figure out really.
I've tryed to google for some good definition of what they represent and how
they should be used with respect to the asynchroneous callback but couldn't
find too much that would help.

Would someone care to elaborate on this ?
Thanks
Marc
