I'm running 14.04 and I could not set a2dp today. I had it working, but now I have a terrible sound without a2dp. I can select a2dp in the GUI, but it makes no difference and when I go back to those settings, telephone quality is selected. This is the output from cli:
$ pactl list cards short
0 alsa_card.pci-0000_00_1b.0 module-alsa-card.c
4 bluez_card.8C_DE_52_91_9A_AB module-bluetooth-device.c
