This is a short guide to how to send audio from your phone (tested on Android) to your PC (tested on Ubuntu).
I have not found how to enable the functionality in the system settings (PC side)
Support is already implemented in PulseAudio
Now you’ll have to pair the computer with the phone as per normal.
Method 1 – Using GUI (D-FEET)
Use a tool called d-feet, which is available in the Ubuntu repos.
$> sudo apt-get install d-feet
Open d-feet and find your phone device
Click in Connect on org.bluez.AudioSource , and then click Execute in the dialog that will open
Method 2 – Using Script / Command Line
export BTADAPTER=`dbus-send --system --dest=org.bluez --print-reply / org.bluez.Manager.DefaultAdapter | tail -1 | sed 's/^.*"\(.*\)".*$/\1/'` dbus-send --system --dest=org.bluez --type=method_call --print-reply \ $BTADAPTER/dev_1C_56_FE_A3_EC_0C org.bluez.AudioSource.Connect
Now all audio from your phone should be streaming through your computer
