After reading a lot of bug reports and trying several solutions which
helped other people (for example #149), but I am still stuck getting
Ubuntu 14.04 to work with Bose Soundlink Headphones. Host is a Lenovo
Carbon X1 Carbon 3rd gen - having an Intel 7265 card.

I am able to pair, and also can set the A2DP profile for this device.
After a couple of seconds however, the device disconnects and kernel log
has a couple of

[   50.181581] Bluetooth: hci0 SCO packet for unknown connection handle
0

lines. Afterwards, the device rejects re-connection, only re-pairing
will bring it back to a connected state.

The device works fine with other hosts like several Android phones and
tablets, a MacBookAir running OS X, but I also got it running with the
same laptop (!) running Ubuntu 15.04. However, for my work I need to
stick with 14.04 to be compatible with colleagues.

Suspected a bug in the firmware, but I couldn't found newer firmware
than the one already used:

[  760.815953] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq
[  760.895882] Bluetooth: hci0: Intel Bluetooth firmware patch completed and activated

Tried several kernel versions, no luck either.

Anyone with a idea how to fix the "SCO packet for unknown connection
handle" problem?

Bug description:
  Hi,

  I found a bug in Ubuntu 14.04 !

  I tried to pair a bluetooth stereo headset (A2DP compatible). The
  pairing process goes well, but after that I can't select it on the
  audio preferences.

  When I select it, it only shows the last selected item options and don't do anything. (he should switch to the headset output).
  I must mention that it worked very well on Ubuntu 12.04.

  This bug can be in the bluetooth stack or in unity-control-center or
  maybe pulseaudio. I actually have no idea.
