Bug Description
What I expect to happen: audio working like in Ubuntu 14.04
What is happening: programs cannot connect to pulseaudio server, the server itself isn't crashing. For example, pavuctl hangs on "connecting to pulseaudio", and all media applications are doing the same. It sometimes happens that one application (which opened connection to PA earlier) is still playing but new ones can't connect.
pulseaudio -k && pulseaudio
fixes this issue temporarly, until the next time it happens. The problem occurs multiple times per session.
This is happening on 2 systems, one is not my own - a clean xubuntu 16.04 install - and the other is my own, where I tried various tweaks to default.pa to fix the problem. None worked. This happens with a clean default.pa too. I also tried installing oem-audio-
The errors reported in pulseaudio stderr are as following:
E: [alsa-sink-ALC892 Analog] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write.
E: [alsa-sink-ALC892 Analog] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.
E: [alsa-sink-ALC892 Analog] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
