I am failing to get my Logitech H800 headset's mic to work at a better quality than "HFP/CVSD" 8kHz and would like to find out whether it's an intrinsic hardware problem or a config problem.
I'm using pipewire/wireplumber on Ubuntu 22.04.
pactl list cards shows (tried to remove non-relevant lines):

As you can see, a2dp-sink-faststream_duplex claims: sinks: 1, sources: 0 . However, the ports below say that both the input and output are part of the a2dp-sink-faststream_duplex profile.
pactl list sources shows:

which looks weird, since even though it is the input/mic/source, it shows profile = "a2dp-sink".
Is there anything I can do to fix this or am I stuck using this headset in HFP/CVSD "tin can phone" mode?
