I just bought the Billboard Carbon ANC headphones and when pairing the Bluetooth or connecting the cable only the headset is detected but Headphones mic doesn’t. I’m using Manjaro KDE and replaced pulseaudio with piperwire since I installed the system.
After experimenting a bit I noticed that if I changed the default codec in plasma settings from High Fidelity Playback A2DP Sink, codec SBC to Headset Head Unit (HSP/HPF, codec CVSD) then the mic is detected and works but no sound is coming to the headset.
