Hopefully this makes sense....
I have a PS3, 360 and plasma TV. Sound is currently running through the TV's standard built in speakers (boo)
If I want to run it via a 5.1 system I would do so via an optical cable. However most systems I have looked at only seem to have 1 optical input.
My question is: Can I run the optical from the TV to the 5.1 system and get true 5.1 whilst playing Xbox / PS3 or do I need to run an optical cable from each device?
