For a while now I haven't been able to access both mic and earphones of this headset with the plug/unplug/replug dance.
HOWEVER, I've noticed that both are correctly detected by #ALSA (alsamixer shows both, at least), so this appears to be a problem further down the line (either in #PulseAudio or #Pipewire).
I don't suppose anyone has an idea how to debug (or even better solve) this? Google isn't being helpful.
