Soudbar HTL2160/12 : big echo with surround

[gabrieldefrance]

Hello,

I have bought the soudbar htl2160/12 with serial number kx1a1246134447.

When i activate the surround, there is a bigh echo, it s inaudible !
Without the surround the echo is less important.



The subwoofer is on the left, and the sound bar in front of tv.

Sorry if my ensligh is not very very good, i m french.

Tank s everyone....
