Heya!

There's a apparently a bug in the 'multi' plugin. When it is used it will pretty often signal POLLOUT when used with snd_pcm_poll_descriptors_revents() and the subsequent call to snd_pcm_update_avail() will still return 0. Doesn't look right to me.

Doesn't look right, indeed. On which system setup does it happen? Can you reproduce it via a combination of dummy driver so that I can test it on my system, too?

thanks,
