pc as headset linux mint

I've found a way to use pc like an headset with Android phone (for making callings).
!!! I've use pulseaudio from jessie-backports: I don't know how much this takes risks ;-) !!!

In /etc/apt/sources.list add:

deb http://ftp.jp.debian.org/debian/ jessie-backports main contrib non-free
deb-src http://ftp.jp.debian.org/debian/ jessie-backports main contrib non-free

$ sudo apt-get update
$ sudo apt-get install pulseaudio=7.1-2~bpo8+1 pulseaudio-utils=7.1-2~bpo8+1 \
    pulseaudio-module-x11=7.1-2~bpo8+1 pulseaudio-module-bluetooth=7.1-2~bpo8+1 \
    libpulse-mainloop-glib0=7.1-2~bpo8+1 libpulsedsp=7.1-2~bpo8+1 libpulse0=7.1-2~bpo8+1 \
    libpulse0:i386=7.1-2~bpo8+1

create a file (with same ownership of /var/lib/gdm3) (create directories if necessary)
/var/lib/gdm3/.config/pulse/client.conf

autospawn = no
daemon-binary = /bin/true

Install "ofono"

in /etc/pulse/default.pa 
modify the line:
load-module module-bluetooth-discover
in:
load-module module-bluetooth-discover headset=ofono

Restart pulseaudio:
killall -9 pulseaudio
(is not necessary "pulseaudio --start" because from pulseaudio 6 it will restart automatically)

For now it seems that:
- if in /etc/pulse/default.pa you have add "headset=ofono" you will have the headset;
- if not you will have a2dp (restart pulseaudio every time).

Good luck
