[Pkg-utopia-maintainers] Bug#1055266: pipewire: Changing monitor settings makes HDMI output silent forever

[Eduard Bloch]

Package: pipewire
Version: 0.3.84-1
Severity: important

Dear Maintainer,

   * What led up to the situation?

My speakers are connected via 3.5mm jack to monitor, which is connected
via docking station to laptop. When connecting the laptop for
the first time, the HDMI output works.

BUT: I need to change the monitor settings with xrandr, i.e. fix the RGB
range or refresh rate (it's a 144Hz monitor after all). And when I do
change the refresh rate, the picture of the monitor is lost for a couple
of seconds. Afterwards, almost everything works and I have my smooth 144Hz.

BUT: audio output is BROKEN. 

   * What was the outcome of this action?

There is NO SOUND comming out of the speaker anymore!! I still see the
devices there in pavucontrol, it seems to be in the same state as before
and "...  HDMI output" is selected as before. I can still control it,
but it remains SILENT.

   * What outcome did you expect instead?

TO NOT BREAK! Restore the settings and continue with sound output after
the display connection was reestablished.

Best regards,
Eduard.
