I have a Roku 2 XD currently connected to my SDTV by way of the ole red/white/yellow RCA's. I get a very surprisingly good picture from that little RCA cable, but look forward to the day I can connect by way of the HDMI connection to a HDTV. I do have a very nice surround system and currently connect to it from my TV audio out when I want to hear Roku programming in surround sound. The processor gives me options of how to listen to that signal.
What I looked into recently was a cable on eBay (for XBox) that was (I thought) normal HDMI on one end and toslink on the other. It turned out, on closer look, that the HDMI end was a proprietary XBox connector and would not fit my Roku HDMI out.
Does any one know how I could use the HDMI out of my Roku to get 5.1 surround to a toslink input on my system? I would continue using the RCA connection for video and audio to my TV.
I am finding there is now a encoding called Dolby Digital Plus that I'm sure my ten year old surround system never heard of, so I have my doubts I can make this work, but........
