Setting default application volumes in pipewire/wireplumber

lxs602 · 05-03-2024, 03:58 PM

Hi,

I have a problem with individual applications keep resetting volume to 46% when they are closed and reopened. I tried attaching a .gif animation, but it doesn't play, so here is a link.

It only happens on Budgie session (Ubuntu 24.04 new install), and only with USB speakers. I have posted the problem elsewhere. (Interestingly, firefox instead defaults to 100%).

I asked on pipewire IRC, and also here, but with no response, so I am posting here if hopefully someone can help.

Thanks.

For mpv create/edit ~/.config/mpv/mpv.conf
and add the desired start up level

Code:

volume=100

Hi, this is independent (outside) the internal mpv volume, which is set to 100%.

Streams are defaulting to 46%, even though the setting is 100% on wireplumber.

wpctl get-volume 81
Volume: 0.46

wpctl get-volume 84
Volume: 0.46

wpctl get-volume 88
Volume: 0.46

For pipewire clients, I'm not sure it is currently possible. FWIW, a similar thread
https://forum.manjaro.org/t/how-to-s...olume/115016/3

For pulseaudio clients it is possible to use 'module-match' as described here
https://bbs.archlinux.org/viewtopic....29219#p2129219
https://www.freedesktop.org/wiki/Sof.../#module-match

However, pipewire has not yet implemented this module (for pipewire-pulse API) based on what I read here
https://docs.pipewire.org/page_pulse_modules.html

So it fails as expected

Code:

pactl load-module module-match
Failure: No such entity

A feature request is likely needed to help progress this.
