I have experimental patches to add async support to ioplug. With a quick test using jack plugin, it seems working somehow. Will post them alsa-devel now.

Thank you! I tested these with Firefox + Flash 9 + Pulseaudio, and while sound output works, quitting any Flash application will freeze firefox.

It's a showstopper, then. Could you figure out in which code does it freeze? My change is just to add async call, so it sounds like that another hidden bug is hit by my change...

That freeze is an unfixable race condition that Flash has when shutting down audio.

See the explanation down on http://pulseaudio.org/ticket/267
