Bluetooth headset not working as microphone (A2DP sink, HSP/HFP)

Hi
I've got a Bluetooth headset, it comes with a microphone. I've tested the microphone on my android device and it works.

I followed these steps to connect to my BT headset
https://wiki.archlinux.org/index.php/Bl … on_via_CLI

But, pulseaudio shows that a2dp sink and HSP/HFP is unavailable for the device

The journal also mentions something but I don't know what to make out of it.

I've asked on the IRC and Googled a lot but in vein.
Also, this is not specific to the BT headset. I've tried multiple headset but same results. Please help.
I'm on 5.6.8-arch1-1.

Hello,

have you got installed this package called as  "pavucontrol" in your system? If you do, open this volume control from Multimedia menu, and check in that new volume settings windows> input devices>Headset microphone

Hi.
Yes, I do have the graphical frontend to pulse. Though the microphone (using headset) appears unavailable there.

Using Gnome/GDM by any chance?

Did you read this manually profile when A2dp is not working with PA or is unavailable ? https://wiki.archlinux.org/index.php/Bl … PulseAudio

No, not using Gnome/GDM. i3 here.
I read the manual. A2DP source and HSP/HFP are unavailable, sink is fine.

I am also having the problem, Bluetooth headset but microphone does not work.

Jul 03 01:47:22 microglia bluetoothd[738]: a2dp-source profile connect failed for F8:8A:3C:32:CE:D9: Device or resource busy
Jul 03 01:47:22 microglia bluetoothd[738]: Control: Refusing unexpected connect

I noticed that the wiki states:

Currently, Arch Linux supports the A2DP profile (Audio Sink) for remote audio playback with the default installation.

https://wiki.archlinux.org/index.php/Bluetooth_headset

Could it be intentional that Audio Source is not mentioned?
Maybe a2dp-source via bluetooth headset is just not supported by Linux atm. I tried on a Fedora 32 live and the Pulseaudio A2DP source profile is still unavailable.
