do I understand you correctly, that if you pair your headphones, the sound coming from your TVs inbuild speakers is delayed if you compare it to the headphone sound?
Re: Echo heard on TV when using A2DP Bluetooth headphones and TV sound simultaneously
I found a "temp fix" , go to the sound settings and adjust balance to the left or right speaker to Max. It helps keep down echo on TV. Does not affect headphone sound.
(I did it during playback with both TV speakers and Bluetooth headphones on, via Action Menu-Sound Adjustment-Advanced - Common - Balance)
After buying a Sony Bravia 65a1 and Sony 1000 mk 2 headphones in November 2017 I found that like you when I paired them I found that the t v echoed badly.After speaking to Sony and trying three pair of headphones in the shops 65a1 t v they all had the same problem.I have been told Sony are working on the problem.Im waiting to hear back from them.
The different audio paths obviously have a slightly different audio delay. Lip sync has always been a problem on Sony. One might be better than the other in that respect.
But why would you want to have audio coming from speakers and headphones in parallel?
