Can't change profile to HSP for Bluetooth headset
Solution 1
Sad story,
Seems that your bluetooth card has not a fully compatible driver with bluez or whatever as mine :(.
I solved following this guide and building two stupid scripts
Getting ready
Install ofono
sudo apt install ofono
Config pulseaudio to use ofono:
- Goto /etc/pulse/default.pa find the line load-module module-bluetooth-discover and change it in load-module module-bluetooth-discover headset=ofono.
- Add the user pulse to group bluetooth to grant the permission: sudo usermod -aG bluetooth pulse (probably it's already correct)
- VERY IMPORTANT: To grant the permission, add this to /etc/dbus-1/system.d/ofono.conf (add this before </busconfig>):
<policy user="pulse"> <allow send_destination="org.ofono"/> </policy>
Provide phonesim to ofono.
In order to make ofono work, you have to provide a modem to it! You can install a modem emulator called phonesim (implemented by ofono) to make it work:
- install ofono-phonesim (in some distros it is called phonesim). in Ubuntu 18.04 (for Ubuntu 20.04 follow this link):
sudo apt install ofono-phonesim
- Configure phonesim by adding the following lines to /etc/ofono/phonesim.conf:
[phonesim]
Driver=phonesim
Address=127.0.0.1
Port=12345
- Restart ofono:
sudo systemctl restart ofono.service
- Clone ofono repository (contains useful scripts)
git clone git://git.kernel.org/pub/scm/network/ofono/ofono.git destination/path
Then, every time you want to enable hfp/hsp:
ofono-phonesim -p 12345 /usr/share/phonesim/default.xml &
then use
path/to/cloned/repo/test/enable-modem /phonesim
then restart pulseaudio with
pulseaudio --kill && pulseaudio --start
Now you should see a microphone device.
When you want to go back to a2dp:
path/to/cloned/repo/test/disable-modem /phonesim
then restart pulseaudio with
pulseaudio --kill && pulseaudio --start
eventually restart pulseeffects with
pulseeffects --quit && pulseeffects &
Lately i'm not using this because it's not always working, and so using a jack is faster.
Hope it helps :)

I don't have enough reputation to comment, so put this as an answer.

After removing headset=ofono
from
load-module module-bluetooth-discover headset=ofono
and restarting pulseaudio
the speakers work again with microphone in Ubuntu 20.04.

I bought a Bluetooth headset cause I'm tired of wires. The headset supports A2DP, HSP, HFP and AVRCP.
I paired the headset correctly, and was greeted with the microphone not showing in the input tab of sound settings. This makes sense since the headset was in A2DP. I tried to change it to HSP/HFP in able use the microphone, but nothing seemed to happened.
Then I tried to do all of this via Blueman. Blueman complained
Failed to change profile to headset_head_unit
.I've tried unpairing the device and pairing it again, setting the profile to off and then to HSP/HFP, but the same thing happens. It seems like I can only switch to A2DP, which only allows to hear, not use the mic.
In case it's necessary, the headset model is AV620 by Avenzo.
