[Bug 274950] Re: Look into switching to bluez 4.x

[Mario Limonciello]

Per the comments about audio, i've done an upload of bluez
4.9-0ubuntu1~ppa2 and alsa-lib-1.0.17a-0ubuntu4~ppa1.  These will create
an additional ALSA device that is usable when paired.  Test it with
aplay:

aplay -D headset $FILE

aplay will receive IO errors when not paired if you use this device.
There are no side effects with regular usage (not headset device).  When
the device is paired but out of range, there will be delayed responses
to the applications trying to use it as IO errors time out.

** Also affects: alsa-lib (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: alsa-lib (Ubuntu)
     Assignee: (unassigned) => Mario Limonciello (superm1)
       Status: New => In Progress

** Description changed:

  BlueZ 4.x resolves two regressions that are seen in the 3.x stack on
  Intrepid.
  
  Regressions solved
  -------
  * Keyboards aren't able to pair in the UI.
     - Reverting to an earlier release of bluez-utils is not a good solution as a lot of bugs were fixed related to Symbian OBEX by coming up to 3.36.
     - This happens with the latest version of bluez-gnome (0.28) as well.
  
  * Broken services tab
    - In the 3.x stack, the services tab is unfortunately the only way to activate new devices.
    - This is fixed in bluez-gnome 0.28 or anything later.  However you need to switch to a package in the 1.x series when using the Bluez 4.x stack.
  
  Newer features
  ------
  The 4.x version brings an additional UI element, a pairing wizard.  This may cause problems for documentation teams, but considering the previous UI was not intuitive, there likely hasn't been a lot of documentation on it.
  
  
  Testing
  ------
  The entire stack that needs to be changed for this bug is available on the Bluetooth team testing PPA at http://launchpad.net/~bluetooth/+archive .
   * Builds are all verified functional for i386, amd64, lpia
   * These builds have all been test installed by adding the PPA to an up to date Intrepid and doing a dist-upgrade.
   * An upgrade from a base install of hardy to one of intrepid while using the PPA as an active repository was also tested.  Modifications had to be made to update-manager to test this behavior (since the PPA is not authenticated).  There were no upgrade issues.
   * Functionality has been verified for keyboards, mice using both Rocketfish & Apple keyboards and mice.
   * Functionality has been verified for OBEX browsing, OBEX sending, and DUN via rfcomm on a Blackberry 8130.
+  * Functionality has been verified for Audio headsets using the "headset" device.
