--- Comment #7 from Rafał Mużyło galtgendo@o2.pl 2008-05-18 06:50:04 --- And, while I can't really check that (unless I would fetch git of alsa-plugins, I'll think about it), failure with my patch may be simply related to the fact that current alsa-pulse plugin doesn't respect start_threshold (https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3944), while the one without my patch is definitely related to your incorrect use of snd_pcm_delay.
