    hoowaaaa , i managed to make it work after surfing the internet for two days ..

    first of all you need to write down in terminal the following :
    nano /etc/bluetooth/audio.conf
    then you have to add this line :

    now restart your bluetooth serivice by writing this in terminal :

    service bluetooth restart
    now pair and connect your bluetooth device using "bluetoothctl" or "blueman-manager", if your device already paired and connected , you don't need to pair it again after restarting the bluetooth service ...

    now write down in terminal :
    pactl list cards short
    you should get something begins with "bluez_card.00" with the index number on the left for each card

    and now with the final command :

    pactl set-card-profile [index_number] a2dp_sink
    congratulations now it's working ..
    my os info : Linux kali 4.9.0-kali4-amd64 #1 SMP Debian 4.9.30-1kali1 (2017-06-06) x86_64 GNU/Linux
    my Bluetooth module : module-bluez5-device.c

    i hope you close this thread ... thanks
