I've connected my FOX T2 to my surround sound system using an optical cable.
When I view a SD channel I get the sound out of the surround sound but I get no sound out of the TV which is fine.
But when I view a HD channel I get the sound out of the surround sound and also the same sound out of me TV speakers so I have to mute the TV.
This also happens if I record a program on a HD channel.
Why do I get sound out the surround sound and TV when viewing a HD channel but only from the surround sound when viewing a SD channel?
Thanks
Jon
