As described in the title 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.
I'm not sure if the delay is caused by the Bluetooth standard, the A2PD protocol, the A2DP implementation on Ubuntu 12.04, or the Belkin Z73 Bluetooth Receiver.
Anyways, is this a normal lag? Is there a way to play audio over Bluetooth without any noticeable latency?
