Volume of USB Headset is stuck at 32% in alsamixer
I'm using pipewire-pulse on Arch Linux. I just recently switched from pulseaudio to pipewire. I have to manually increase the volume of the volume of the headset from 32% to 100%. When I remove the USB headset and plug it back in again, the volume is again reset to 32%.
The headset is a Logitech H390. In alsa-mixer, the volume of the outputs do not change when I change the volume of the device via pavucontrol. The same goes for the volume of the inputs. This is very different from the Intel HDA soundcard, where the volume changes in alsamixer when controlling it via pavucontrol.
In alsa-mixer, the USB headset has 2 playback channels (Heaphone and Mic) and 1 input channel (Mic).
