Well I'm puzzled. I've been through all the settings on the TV and the youview box and I can't see anything relevant. All I managed to do was (a) get stuck in pip mode then (b) get it the other way round so that pressing the red button on the youview remote switched the sound box on when switching the you view box off!
Although I don't really see the TV as particularly relevant, except that it is taking the signal from the youview box via HDMI in and spitting it out via spdif to the sound box. Could a youview software update have changed the signal format?
The sound box doesn't have any settings as such, so there's nothing that could have gone wrong on that.
So, all a bit of a mistery which I guess I'll just have to live with. Not the end of the world.
