[Bug 1211102] [NEW] Get rid of 0.5s latency when playing audio over Bluetooth with A2DP

[Diego Carrera Gallego]

Public bug reported:

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description:	Ubuntu 13.04
Release:	13.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center

  Instalados: 4.101- 0ubuntu8b1
  Candidato:  4.101-0ubuntu8b1

 *** 4.101-0ubuntu8b1 0
        500 http://es.archive.ubuntu.com/ubuntu/ raring/main amd64 Packages
        100 /var/lib/dpkg/status

3) What you expected to happen
The audio always is sync when i listen music on my bluetooth device 
If i listen music or have a videoconference with skype.. it receive audio perfectly without delay.

4) What happened instead
 I experience a half a second delay when playing audio over Bluetooth with A2DP.
This makes watching movies not possible as the sound is not synchronised with the video.

+ If i listen music, then stop about 5 minutes and then restart to listen music, it gets work bad.
+ If i get a skype videoconference, it gets too much delay.
