audio hook up Roamio basic

Can I run the HDMI to my tv and also run the optical digital to an older receiver (does not have HDMI)? Will the both output audio simultaneously?

Also the yellow RCA plug says A/V, does that mean audio or video. Yellow used to mean audio in the old days. Could I use a stereo Rca wire and then a splitter to go to left and right inputs on this old receiver. ( if dig optical is not an option)

Thanks



My Roamio won't arrive until next tues so I am just trying to be ready.

I did not know it did not have rca outs until I found a pic of the rear of the unit
