We have been using the Arc in surround setup for quite a long while, but recently we have been experiencing problems that it echo’s at times. It is very sporadic. But the two back speakers (Ones) are slightly out of sync. It always happens when watching TV, but today for the first time also happened playing music.
The solution for it is to basically to turn the arc off and on (i.e. pull the power and reconnect it). Then it all works perfectly again… sometimes for a few weeks, sometimes for a few days.
The Arc itself is connected wired and the two Ones and the Sub are connected through Wifi. We have a Boost.
Anyone have any experience with this and perhaps know a solution? I’ve not changes any settings. I’ve played with the lip sych setting when it happens, but that seems unrelated.
