Bug#767167: gnome-control-center: Sound output device disappears after suspend/resume

[Michal Sojka]

Package: gnome-control-center
Version: 1:3.14.1-1 1:3.14.0-1
Severity: normal

Dear Maintainer,

after fresh boot of my computer, output tab of "gnome-control-center
sound" (GCCS) shows two output devices: HDMI/DisplayPort and LineOut.
After suspend/resume, the LineOut device always disappears and
sometimes (not always) no sound goes out of the LineOut device. The
expected state is that both devices are still visible in GCCS and
sound always goes from LineOut.

In the "no sound" case (or when I select HDMI/DiplayPort manually in
GCCS), there is no way to get sound out of LineOut device again by
only using GCCS. It is, however, possible to use pavucontrol to
restore the sound output, but the LineOut device is still missing in
GCCS. The sound can be restored by going to the Configuration tab of
pavucontrol and changing Profile of "Built-in Audio" from "Digital
Stereo (HDMI) Output + Analog Stereo Input" to "Analog Stereo Output
(unplugged)". Note that the LineOut device (known as Built-in Audio in
pavucontrol) does not have HDMI output and HDMI does not appear in
pavucontrol Profile list box before suspend/resume.

Thank you.
-Michal
