Comment # 13 on bug 1228057 from Takashi Iwai

Thanks.  The pactl shows that this headset has no duplex profile by some
reason.

So it looks rather like a bug in pipewire or wireplumber.
Adding Antonio to Cc.

Meanwhile, Ricardo, if you haven't tested the latest pipewire 1.2.1 (that
should be available in OBS multimedia:libs project), could you try it out? 
Just to be sure.
