I'm using a DVI cord for my video connection with a toslink to my surround sound system. I am also trying to run RCA for sound from my 811 to my TV for situations where I don't want to use my surround sound. When I do this I'm running it from output 2 I beleive (output one is going to my VCR), into the back of my tv... when I do this I get sound but am unable to control the volume on it.... thoughts?
