I'm getting a new 55" TV and it has an optical digital audio output. I have Comcast cable with their HD DVR box, and it has a digital audio output as well. What is the best way to wire the sound of my TV to my receiver? Should I take the audio from the TV to the receiver from it's optical line, or should I take the audio from the cable box to the receiver? If I take it from the TV to the receiver...then will the volume go up/down with the commands from the regular TV remote as if I was turning the TV speakers up/down? That would be nice so that I don't have to use the receiver remote for the sound and the TV remote for changing channels, etc.
Thanks in advance for your advice!
