Since, the Fedora 20 is migrating to Bluez5  and there is no support for bluetooth in Mate Desktop in Fedora 20. I was about to find some workaround to use bluetooth headset. Bluedevil is currently not working.
$ bluetoothctl [bluetooth]# power off [bluetooth]# power on [bluetooth]# agent on [bluetooth]# connect 20:16:D8:5A:19:DC
The selection of audio output is task for pulse audio. The mate-volume-control, standard audio configuration tool, cannot select audio output.
