I would start with using your distro's pulse package and checking both
the system logs and the pulseaudio logs. I would expect there to be some

I'm back to distro's pulse package. When the headset_audio_gateway capability is switch to not available, the pulse audio logs this:

Is "card_2" the card "2" display when typing pactl list cards? Beacause if yes, this is an internal audio-card that I am not using. I' using an USB in/out audio card
