Yes. I assume you have your TV connected to the cable/ sat box via HDMI. Whether or not you use the optical out from the TV or box is up to you. I also have a non-HDMI receiver in use. Some sources (current Blu-Ray DVDs) may not provide the full 5.1 or 6.1 signal your receiver can use. You'll be stuck with basic surround. This happens with my Yamaha RX-V1 with some sources. I run the HDMI signals from the sources into the TV, which is essentially only a monitor. The audio from my cable box is COAX (not optical) and my Denon Blu-Ray is optical. HDMI systems automatically switch to the source where there's a signal, which is nice, but you will have to manually select the source for your TV input AND your receiver, which can be a pain unless you use a remote with macro features that you program to perform those tasks. Hope this helps!
