Yesterday I upgraded my playbase to an Arc, having connected everything, it was all up and running fine last night. This morning, I had no sound coming from the TV (HDMI 1), also I had no sound when I switched to the PS5 (HDMI 2). The ARC is connected to (HDMI 3 eARC), and I have a Himedia Q10 pro conected to (HDMI 4), these are the only HDMI ports available.

When I played a movie through my media player I had sound, then when I went back to the TV and PS5 I also have sound. But once I have turned everything off for a short while and come back to it, it’s happens again, no sound to both the TV and PS.

I have changed the ports around, disconnected everything, unplugged and replugged everything. The only time it works is when the HDMI cable to the media player is disconnected, even if I remove the power connector there is still the issue.

Anyone have any idea how to fix this? thanks.
