[alsa-devel] alsa-jack issues

Hello,

A recent change in alsa-plugins 1.0.28 alsa-jack has changed the poll semantics.
This breaks audacious and mpv, perhaps more applications.

The regression is caused by:
Commit: 9217377337cdceb62abeb5969112b738bb5cd551
jack: fix polling and recovering


This might or might not be related to lack of
snd_pcm_poll_descriptor_revents call or the use of a timer instead of
repolling.

Another major problem is the lack of handling of DRAINING state. This
breaks short sample playback with aplay and possibly other
applications. That also was present in older alsa-jack and is not a
regression.
