All of the Bluetooth headphones I have, include microphones. Only two
models (Inland 87099 and Creative) have the electronics to support the
HSP/HFP profile.
My intent was to use the headphone mic in one of these for online
meetings (Zoom, Jitsi, etc.), but under Debian, this isn't working with
the installed software. pulseaudio-module-bluetooth is installed, as is
ofono, blueman, bluez-tools, bluez, bluez-obexd and libbluetooth3.
This exact same setup worked when I had TDE/PCLinuxOS installed with the
same packages as above (the libbluetooth package might have been named
differently).
Under PCLOS, I used the PC's on-board audio at the time. I do not know
if the new PCI-E sound card I have now, has anything to do with this
issue, even though the card's /Front Microphone (unplugged)/ entry shows
activity in the PA volume control, until I mute it.
With either the Inland or Creative headphones connected on the HSP/HFP
profile: no mic, no audio in the headphones, no audio from the PC
speakers. Changing profile to A2DP resumes the audio from the
headphones, the headphone mics never worked under A2DP.
pacmd list-sink-inputs lists one input, the headphones.
list-source-outputs indicated 0 (zero) source outputs available.
