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.
use jack :) then you don't have to care about that.
iiuc, the buffer size is in samples, and period defines how many buffers
are used - i guess this is per hardware interrupt, but i may be wrong.
high-end cards can do bufsize=32 and p=2. most cards should be able to
easily do 512/3. if latency is not an issue, you can use 4096/3 to save
cycles.
