Public bug reported:

While playing a youtube video, starting up another audio playback (in
this case, in Rhythmbox) causes the video player to crash.

I expected the video (with its audio track) to continue playback without
crashing, while Rhythmbox gets mixed in as a second, concurrent audio
source.

Instead what happens is that I start playing a track in Rhythmbox, that
first track fails with an error "Failed to open output device:
pa_stream_writable_size() failed: Connection terminated", at this point
the youtube video crashes and then the next track in Rhythmbox begins to
play without pulseaudio.

Running pulseaudio -vvvv, I can see that alsa-sink.c is for some reason
processing lots of rewinds shortly before there is an implicit underrun
reported, then pulseaudio dies.


Ubuntu release: 15.10 wily
Pulseaudio package version: 1:6.0-0ubuntu13

I had no problems with audio on my previous install on this hardware
(14.04 LTS, clean install). Ever since I did a clean install of 15.10 on
the same hardware I've had problems with audio and pulseaudio.

My audio setup is analogue 5.1 output on ALC889A (Gigabyte GA-MA790GP-
DS4H onboard HDA) using snd_intel_hda; there is also HDMI audio output
hardware detected but which I'm not using. I've had to install
pavucontrol to select my analogue output as it doesn't show up in the
standard sound settings (only the digital output).

I had modified /etc/pulse/daemon.conf to adjust default-fragments and
default-fragment-size-msec to fix glitchy audio in a game, and then
modified them back to default values when that stopped music players
from working - I was constantly getting the same pa_stream_writable_size
error as above.

Adding then removing "options snd-hda-intel model=intel-alc889a" from
/etc/modprobe.d/alsa-base.conf has made no difference.

There could be a timer problem - when booting up, the boot process
stalls unless I press a key, move the mouse or add "nolapic_timer" to
grub boot options (which I'm running with at the moment); the pulseaudio
log refers to a lack of high resolution timers and disabling timer-based
scheduling. I'm going to try taking that out and see whether that makes
a difference.
