360 box - audio sometimes drops out from sound bar (HDMI ARC)
I have a Hisense TV, Samsung HW-Q60T sound bar and new Virgin 360 box. All works well but occasionally (like 2 or 3 times during the evening) the sound switches from coming out of my sound bar and reverts to coming out of my TV speakers (with a message on my screen saying ARC device has been disconnected). If I switch the sound bar OFF and then switch it back ON again then all is ok again and audio comes out of my sound bar (at least for a while, anyway). This didn't happen when I had the Tivo box and has only just started doing this since getting the new 360 box. I have not changed the way the 3 units are connected together with cables, that is still the same: TV to sound bar using HDMI ARC to HDMI ARC sockets. TV to Virgin 360 box using HDMI to HDMI sockets. I'm not very savvy when it comes to this new way of connecting various devices together but conclude that it must be some software issue or a settings issue but have tried various settings and nothing seems to make any difference. The sound still drops out now and again. Can anyone help? What am I doing wrong?
