[Pkg-utopia-maintainers] Bug#1108674: wireplumber: Audio resets to 100% volume after every suspend or power off

[Fainche]

Package: wireplumber
Version: 0.5.8-2
Severity: important
X-Debbugs-Cc: old-attic-breeches at duck.com

Dear Maintainer,

Every time I suspend or power off, upon resume the audio volume is 100%. GNOME still shows what the audio is supposed to be set at, and it corrects itself once I touch the slider. Muting and unmuting does not fix it, only touching the slider does.
Leaving the audio on mute does not prevent this issue. The sound will be 100% volume despite being muted. I can reproduce the same problem on Sway, so it's not a GNOME issue.

The audio output is just my monitor speakers. The audio device is Renoir Radeon High Definition Audio Controller.

Bug does not exist on Debian 12. I've had to disable automatic suspend to protect my ears.
