[Pkg-alsa-devel] Bug#813446: Upgrade causes pulseaudio to fail until restarted

[Josh Triplett]

Package: libasound2
Version: 1.1.0-1
Severity: important

I don't know whether this bug lies in libasound2, libasound2-plugins, or
alsa-utils; reporting it here because it seems like the most likely
candidate.

I just upgraded the following packages:

[UPGRADE] alsa-utils:amd64 1.0.29-1+b1 -> 1.1.0-1
[UPGRADE] libasound2:amd64 1.0.29-1 -> 1.1.0-1
[UPGRADE] libasound2-data:amd64 1.0.29-1 -> 1.1.0-1
[UPGRADE] libasound2-plugins:amd64 1.0.29-1 -> 1.1.0-1

Immediately after doing so, pulseaudio started logging the following
error:

Feb 01 20:14:28 x pulseaudio[583]: [alsa-sink-ALC3232 Analog] alsa-sink.c: Error opening PCM device front:1: Invalid argument
Feb 01 20:14:28 x pulseaudio[583]: [alsa-sink-ALC3232 Analog] alsa-sink.c: Error opening PCM device front:1: Invalid argument
Feb 01 20:14:30 x pulseaudio[583]: [alsa-sink-ALC3232 Analog] alsa-sink.c: Error opening PCM device front:1: Invalid argument
Feb 01 20:14:30 x pulseaudio[583]: [alsa-sink-ALC3232 Analog] alsa-sink.c: Error opening PCM device front:1: Invalid argument

And attempting to play any audio via pulse (for instance, using mpv)
would fail to play audio, and stall out.  (The audio didn't just go
silent; pulseaudio didn't accept audio, breaking applications and
causing them to not progress.)

Restarting my session did not fix that problem, because pulseaudio stuck
around and got reused by the next session.  I had to kill pulseaudio so
it would respawn, at which point audio started working again.
