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

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.
