I have been trying to bring avrcp control up from my ubuntu desktop to control the music played on my mobile. Bluetooth Stack Used: Bluez 4.101
But i am not seeing the intefaces org.bluez.MediaTransport or Org.Bluez.Control enable on Dbus. What configuration i need to edit in order to get these interfaces available ?\ Please help.

To the best of my knowledge AVRCP controller role (CT) is only partially implemented in Bluez 4, in the form of VolumeUp() and VolumeDown() methods. These can be found in the org.bluez.control interface which you can find at /org/bluez/<pid of bluetoothd>/hci0/dev_<BD_ADDR>. I did not have to edit any configuration files to see that interface.
As an example, executing the following will give you the track information:
$ qdbus --system org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/player0 org.bluez.MediaPlayer1.Track
Album: Lemanis
Artist: Spaceslug
Duration: 464945
Genre: NumberOfTracks: 0
Title: Proton Lander
TrackNumber: 0
You can press tab after qdbus --system org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/player0 to see all the options:
you can try following: run the script "simple-endpoint sbcsink" and then you should be able to make the basic AVRCP functions(ver. 1.0=play pause, next, etc), if you don't know the interfaces for this, uses D-Feet and check it out!!
