change the key control for volume?

The problem is that my keyboard's volume keys are configured to control kmix, which is Trinity's native sound mixer (based on KDE 3). Even though I'm now using PipeWire (and pavucontrol for the graphical interface), pressing those keys still sends commands to kmix (or attempts to launch/control it).

I already searched for Trinity's keyboard shortcuts and accessibility, but I don't know what it is or if it has a technical name.

As always, I'd appreciate any help or suggestions.

Pipewire is a sound server and in fact will control kmix directly. You dont really need to use pavucontrol as thats involved with Pulseaudio which you dont need if youre using Pipewire. Pipewire maintaining the link to the kmix controls/gui is perfectly normal.

I want PavuControl to take control of the sound and disable Kmix. Why doesn't it respond when I use the volume keys when using HDMI or Bluetooth? 
In the worst case, change the audio mixer

Re: change the key control for volume?

Im curious as Pulseaudio is the default in Trinity, so why did you install Pipewire?  Pavucontrol can work with Pulseaudio and kmix(iffy with Pipewire), if Pulseaudio is the main sound server. Pipewire provides an emulation layer for Pulseaudio but there tends to be issues at times.

Because pulseaudio sometimes doesn't open correctly, that's why I installed pavucontrol and since I use Bluetooth a lot, pulseaudio didn't manage that technical part well, much less kmix. On the other hand, pavucontrol and pipewire work great for me, that's why

Re: change the key control for volume?

Gotcha, thanks for explaining, but Pipewire will continue  to send commands to kmix which is a normal behavior. Replacing the mixer wont change that at least in my experience.
