it's not working on my system (i tried 64, 128, 256) ... but playing
with the different settings, i figured out, that i can't change the
number of periods in the hardware buffer ... it's always 2 times the
number of frames per period ...
jack returns as error message:
ALSA: cannot set number of periods to 1 for capture
ALSA: cannot configure playback channel
cannot load driver module alsa
is it possible that this is the problem? i don't understand how the
driver works but if the hardware buffer always gets one block instead of
two and plays it back the whole hardware buffer the samples would be
on the other hand the distortion i hear is not related to the block
size... (btw, i tried to record a sound ... that works fine ...)
nearly giving up the hope ...
