Setup my debian as a headset

[bilogic]

I started googling from here https://askubuntu.com/questions/845195/how-to-set-up-ubuntu-pc-as-bluetooth-headset-to-attend-calls

I'm not sure where to start as I'm unfamiliar with both bluez and alsa.
Any ideas?

Thank you.

If you are not familiar with BlueZ and ALSA, I would recommend to stick with what Debian has by default - PipeWire. To be honest I'm not sure how to enable such feature in PipeWire, but from the desktop point of view using PipeWire will cause you less amount of troubles. If however you really need to use bluez-alsa, then compile it with:

./configure --enable-systemd --enable-upower --enable-msbc --enable-lc3-swb \
  --enable-rfcomm --with-systemdbluealsadargs='-S -p a2dp-sink -p hfp-hf -p hsp-hs'
make && sudo make install

Then enable BlueALSA system service:

sudo systemctl enable bluealsa

And reboot the system (just in case).

Now you should have BlueALSA system service running which will allow you to connect your phone over Bluetooth. For that use some GUI available in Debian, or bluetoothctl in case of headless setup. Refer to the wiki for more info: https://github.com/arkq/bluez-alsa/wiki/Bluetooth-Pairing-And-Connecting

After that you should have two SCO PCMs available for playback and capture. You can use them as follows:

aplay -D bluealsa:PROFILE=SCO ...
arecord -D bluealsa:PROFILE=SCO ...

For more detailed info regarding "bluealsa" ALSA device refer to bluez-alsa manual: https://github.com/arkq/bluez-alsa/blob/master/doc/bluealsa-plugins.7.rst
