Public bug reported:
Audio stopped playing, causing all video playback to also wedge unless
sound output was disabled.
The only meaningful log message was tens of the following in
/var/log/syslog:
[pulseaudio] sink-input.c: Failed to create sink input: sink is
suspended.
Sending pulseaudio a SIGHUP had no effect. Killing it caused it to
restart, however the sound device was no longer present. The sound
device is built-in laptop audio, so it is still physically present,
although it's plausible that the problem is at a lower level. rmmoding
and modprobing snd_hda_intel did not resolve the issue.
