Pulseaudio 13.0, Bluez5 , bluetooth headset HSP/HFP not available

Hello,

I have a bluetooth COWIN E7 headset with microphone. I have been trying to get the headset's microphone to be the audio input to no avail, only the headphones work.
I only have A2DP configuration working, nothing seems to get HSP/HFP to work.
I have searched and gone through countless posts, most of them are very old, but to no avail.

I tried installing oFono and editing bluetooth-module and bluetooth-discovery in /etc/pulse/default.pa as this advises: https://www.reddit.com/r/archlinux/comm … er_bluez5/
I tried setting

 default-sample-rate = 48000 

according to this: https://www.reddit.com/r/archlinux/comm … dset_help/

Nothing worked (of course I rebooted after each change to make sure it applies).

$ pacmd list-cards

            properties:

note: a2dp_sink availability used to say "yes" instead of "unknown" before I started messing around, nonetheless it is working
I'd be grateful for some directions.
Kind regards,

Re: Pulseaudio 13.0, Bluez5 , bluetooth headset HSP/HFP not available

Please use [ code ] [ /code ] tags consistently for any kind of output.

Post your current config files and

journalctl -b --user-unit=pulseaudio
dmesg | grep -i bluetooth
bluetoothctl info FC:58:FA:85:64:E6
journalctl -b --user-unit=pulseaudio

are you using gdm?

There was no pulseaudio process spawned by gdm

Re: Pulseaudio 13.0, Bluez5 , bluetooth headset HSP/HFP not available

Update: I think it's working now.

I reverted everything back to the original state.
Stopped ofono, undid the /etc/pulse/* changes.
And wanted to apply them again one by one.
To my surprise after just applying

default-sample-rate = 48000 

to /etc/pulse/daemon.conf and restarting pulseaudio, it showed this:

$ pacmd list-cards:
  ....
	profiles:
		headset_head_unit: Headset Head Unit (HSP/HFP) (priority 30, available: unknown)
		a2dp_sink: High Fidelity Playback (A2DP Sink) (priority 40, available: yes)
		off: Off (priority 0, available: yes)
 ....

I changed the profile to headset_head_unit and I was able to record through the headset mic ( I walked away to the next room and talked quietly and it was picked up).
Nonetheless, the voice is utterly crappy with occasional loud ticks. I am guessing this is just the nature of this bluetooth profile, since the bandwidth is limited, headphones only work in mono. Let me know if this is NOT how it should be.
I don't know why it didn't work originally. But who cares..
Kind Regards,
