Pavucontrol master volume control buggy with SoundCore mini
Version, Distribution, Desktop Environment: Pipewire 0.3.37 running on XFCE 4.16 (Manjaro running 5.14.7 kernel)
Description of Problem:
The problem I'm having is very similar to this issue, and might have a similar resolution: #1592 (closed)
The SoundCore mini device pairs without a problem and runs fine with A2DP. Sound quality is reasonable. However adjusting the volume with Pavucontrol does nothing, except setting it to 0 turns it off and setting it above 100% increases the volume. Between 0-100 changing the volume doesn't actually change the volume. Below are some diagnostics:
