OK, I have some DTS audio CDs encoded at 24 bit. Do I need to have the receiver set to digital input for the optical cable or 7.1 for the 7.1 analog cables? I know that the CDs are only 5.1, but I have the Panasonic BD10 bluray player connected to the receiver both ways.
When listening to DTS encoded Cds, you should use the optical/coaxial connection. You may get white noise if you use the analog connection. I don't have the Panasonic BD player, so I agree with nick2010, check all of your settings.
