Had the TV and soundbar since December with no ARC sound issues whatsoever - it worked first time and been working for the last 7 months. Switch the TV on and the soundbar would kick in and switch on at the same time displaying TV ARC. Since Sunday the ARC just stopped working altogether. I managed to get it to work again by removing all the HDMI cables and playing around with powering off and on the TV and Soundbar. It only works though until you switch the TV off and then you have to go through the whole crazy procedure again every single time. I've been doing this for the last 3 days and about to throw it all out the window. Any suggestions please?
