No A2DP streaming audio from 12.04 to Bluetooth headset [duplicate]

  • 772

I want to listen to streaming audio from Ubuntu using headset (Bose Bluetooth Headset Series 2). Although Bluetooth connection is established, I haven't been able to hear anything via the headset. How can I work this around in general (I know this might sound brutal but I don't have much knowledge in audio setting on linux) ?

When I use my other Bluetooth headset BlueAnt Q2 (http://www.myblueant.com/products/headsets/q2/index.php) streaming is going. In "Hardware" tab on sound setting panel (not sure how it's officially called but see the image below) shows my headset.

enter image description here

However, Bose one never appears on the same window while it's connected via Bluetooth, except for a few seconds after I manually disconnect the headset (this moment is snapshotted as the image below. When it's connected the Bose BT2 thing is never shown. Btw, with Android phone this headset works just fine).

enter image description here

Bose' manual indicates that 

Make sure the device supports A2DP audio streaming.

So I tried to figure out if A2DP is enabled on my Ubuntu (referring to Can I use my computer as an A2DP receiver / bluetooth speaker?), finding that it's probably available as the result below shows:

  1. I made it work the following way :

    Before going further :

    • Update your system (I'm running 13.10)
    • Remove blueman
    • Install pulseaudio-module-bluetooth, pavucontrol (Utility to set up pulseaudio) and make sure bluez is installed
    • Remove any "Disable=Socket" or "Enable=Socket" entry in file /etc/bluetooth/audio.conf (edit with sudo)

    Steps :

    1. Put device in pairing mode (even if already paired)
    2. Pair the device with your system using default bluetooth manager (blueman should have been removed) or if already paired go to step 3
    3. Select A2DP or Audio Sink connection for the paired device. If it fails try "sudo hciconfig hci0 reset" (where hci0 is your bluetooth device) check scan is ok with hcitool scan then retry this step (do hciconfig -piscan to identify your bluetooth device)
    4. With pavutools, select a2dp in "configuration" tab and your device in "Playback" tab / If a2dp is not selected, try pactl list cards short" to get your device id (1,2,3..) then do pactl set-card-profile X a2dp where X is your device id
    5. If it fails, restart avahi-daemon / bluetooth service and reset device through hciconfig hci0 reset. Check if scan is ok with hcitool scan. Then do steps 3 and 4

  2. You can try blueman application. This app can help you to play audio through A2DP streaming. You just have to mark your device profile as "Audio destination".

    To install, use this command:

    sudo apt-get install blueman

    Open it by typing "blueman" in the dash.

    I'll try to update the answer with necessary screenshot later

  3. see if you have this package installed: pulseaudio-module-bluetooth although the fact that your other BT headset works would suggest so. It is a Mono device though, so it might be subject to different requirements. Also try referring to my question here, I just posted a solution that works for me. @Anwar Shah: Removing Blueman was also a part of that solution, just mentioning it.

  4. Use Blueman with Alsa (packages are much leaner than pulse audio).

    Pair and connect as "Audio sink", you'll hear a 'pop-b-b-b' on the headphones.

    find /etc/alsa.conf or /usr/share/alsa/alsa.conf and append this to it;

    pcm.btheadset {
   type plug
   slave {
       pcm {
           type bluetooth
           device XX:XX:XX:XX:XX:XX
           profile "auto"
       }
   }
   hint {
       show on
       description "BT Headset"
   }
}
ctl.btheadset {
  type bluetooth
}

    The device ID you get from blueman once connected.

    e.g mplayer -ao alsa:device=btheadset mysong.mp3
