Echo heard on TV when using A2DP Bluetooth headphones and TV sound simultaneously

[sj.taylor]

Hi all, I have a KD-55XE8596 running SW PJG6.2671.0070EUA

I wish to be able to use bluetooth headphones and the TV Speaker simultanoeusly, so I have enabled the "Audio to both TV speakers & other device" option.

Unfortunately, as soon as I pair the headphones, I hear an echo through the TV speakers. The tv speakers seem to be playing the real sound AND a slightly delayed sound.

This is really annoying, as I'm sure you can imagine. There are instances where I want to hear the TV from another room, whilst my family continue watching. 

Anybody else experienced this?

EDIT - i think this may be something to do with A/V Sync - it seems the TV is delaying the picture and audio to be synchronised with the BT audio, but unfortunately still plays the original audio alongside the delayed copy!

I've the same issue with a 55XE8505....
After pairing, even if I do unparing, the sound of the tv's speakers have echo !
