Sennheiser MM450-X Bluetooth headset connected but not working

Question

Sennheiser MM450-X Bluetooth headset gets recognized out of the box in Ubuntu 12.04 beta 64-bit. I used this workaround to get past the reconnection problem: Issues with Bluetooth Connections in 11.10

Although the device is successfully connected I am not able to hear any sound into the headphones. Some interference noise is produced instead.

I don't know what you mean with "sound profile". Anyway I didn't set up anything, I left the default settings. — Marco Lackovic, Apr 08 '12 at 09:56

I have solved it by following the steps below:

open the Sound Settings;
select the device in the "Play sound through" pane;
select "High Fidelity Playback (A2DP)" in the "Mode" combo box;
make sure the "Mute" checkbox is unchecked.

Sound profile is the same as your "Mode" box. – Takkat Apr 08 '12 at 18:58
