I have a Beam, Sub and two play 1s connected via Hdmi Arc to Sony KD49XF90. The system works perfectly every day until exactly 3 minutes after midnight, then switches to the internal TV speakers. I've seen a few similar posts in the forum but nothing about the time of day affecting the connection. I assume it's something to do with a setting somewhere, but after trying loads of different things, it still switches without fail. Any help would be appreciared.

I think that's worked this time . Thanks GuitarSuperstar.


Have you tried resetting your TV to the default settings? Just be sure you save any video or audio settings you have madeso you can reset them.
