wireplumber

Hi, I suppose I am in a very specific issue because I don't seem to find a whole lot of informations on it. The context is : I have a linux debian 12 with xfce on a MINIX Z100-0dB (Pipewire 0.3.65 & Pulseaudio module) An SMSL-SU9n is connected to it with USB. (And amp & speakers in the chain)...
