Ubuntu – How permanently remove or disable HSP/HFP bluetooth profile

bluetoothpulseaudioskypesound

I really don't like that, like Skype changes my bluetooth profile automatically to very low quality HSP profile and then just muted the high quality A2DP profile.

So i want to know, is it possible just to remove or disable HSP/HFP profile (pulse audio, bluez) and if it, how?

Internet is full for tutorials how to get HSP/HFP enable, but for my case, that is the problem.

PS: I don't use bluetooth mic, so it is irrelevant to get that working on A2DP, i know that this is a hard thing to get working, so no need extra work on that one.

Copying the most important part, that just disables this "feature" the way like pulseaudio developers intended.

Open (sudo) /etc/pulse/default.pa and add auto_switch=false like this:

### Automatically load driver modules for Bluetooth hardware
ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy auto_switch=false  # <---- !
.endif

Restart pulseaudio by just killing the running instance: pulseaudio -k. Done.You still can switch to the HFP profile, but there is no automatic switching any more.

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` and `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` and `pulseaudio --start

eventually restart pulseeffects with

pulseeffects --quit` and `pulseeffects &

Lately i'm not using this because it's not always working, and so using a jack is faster.

Hope it helps :)
