Sound from bluetooth speaker seems to freeze often and is out of sync with the video

Computer Model: Dell Inspiron N5050 (laptop).

Version of Ubuntu: Have checked in Ubuntu 13.10 and 13.04

Model of Bluetooth speaker: Bose Soundlink mini bluetooth speaker

Description of issue:

Issue 1: Able to pair and connect laptop to the speaker (but the connection breaks after some time and I have to remove the speaker from the laptop bluetooth and repair and reconnect).

Issue 2: When the speaker is connected; if I play a movie, the sound often stops (and pauses the video). Also, the sound and video are out of sync (what I see and what I hear do not match, the sound usually lagging the video).

I have no issues connecting the bluetooth speaker to my Android phone (HTC Wildfire S Android 2.3.5) and Samsung Galaxy tab 2 (10.1 inches) and viewing movies.

I have also tried the solution as mentioned here

sudo gedit /etc/bluetooth/main.conf

and changed the value of RememberPowered from true to false.

Have installed Blueman and BlueZ.

Possible workaround for the sync problem: mplayer has a command-line option to adjust the delay between sound an image, so you could regain sync this way.

The command would be mplayer -delay X /path/to/videofile where X is the delay in seconds. Negative values of X mean that the image will be delayed, and positive values mean the sound will be delayed.
