Bug#953295: Fwd: pulseaudio: Sound stops working after suspend/sleep/resume (does not appear muted but is silent)

[Daniel Boles]

Package: pulseaudio
Version: 13.0-5
Severity: normal


Dear Maintainer,

After I resume my laptop from suspend/sleep, I have no sound. The system
does
not think it is muted, as I can change the volume with hotkeys or sliders,
but
it stops producing any sound until rebooted.

I presume this is a PulseAudio problem because that appears to be what is in
use, and how I control advanced properties of sound that GNOME doesn't have
UI
for.


   * What led up to the situation?

At some point, I updated and then slept the machine. I would guess this was
about a month ago. Unfortunately I don't have more specific details.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I slept/suspended the computer by locking the screen and then closing the
lid
of the laptop.

I also tried, per a discussion on Stack Exchange, to toggle the device to
headphones and back to speakers. This made no difference.


There follows some commands/output that I hope are useful.

Please let me know what else I can provide to help get this fixed. Thanks
for
all your work!

Cheers,
Daniel
