I hope someone can help!
I've had my Xbox attached to my LG computer monitor and it works fine.
I've recently bought a new Toshiba TV and when I plus the Xbox in (via HDMI) I get no sound from the console at all. But the odd thing is, if I plug my Playstation into the same HDMI socket then I DO get sound. And when I take the Xbox back upstairs and plus it back into the LG I get sound ok.
Any ideas what is happening - I want to play Skyrim on my big new TV!
