I have a Pioneer 434 hde, a Sony Davs home cinema and Sky+. My Davs is connected to my plasma box with component leads and my Sky+ connected to my plasma box via RGB scart and an optical lead for 5.1 surround sound. All hunky dorey ! However when I turn off my Davs system I thought the sound would come out of my plasma speakers ( pic and sound thru scart ? ) but this doesnt happen ? I get no sound ? Why is this ? My whole point is that I want my surround sound for watching movies but I want my plasma speakers for normal Sky viewing. So any ideas on how I make it happen ? It's doing my head in !! Thanks in advance and sorry for the "basic" post.
