Comment (by mac <mac20xx@…>):
> The write_size is always fragment_size which is period_size *
output_bytes_per_frame * 2 so by definition it is always a multiple of
period_size.
As long as you're only multiplying you're right
> So if period_size isn't a multiple of "alsa-frames" (as you call it) ;
the issue is within ALSA, not myth...
I called them alsa-frames because they are not the same as frames in
mythtv
I will switch back to mythtv 0.24.1 without patches to give you some
debugging output to you.
> Something that wouldn't surprise me as the type of audio corruption you
describe never occurred with ALSA <= 1.0.22 and only occurs with recent
version of alsa
I don't believe that this is an alsa related problem. Audacious always
worked fine.
