I am new to Roku. I bought a TCL tv and hooked up my home theater. Everything runs through my Onkyo receiver and I have HDMI going to HDMI 1 (ARC). I tried watching some amazon prime video through the app on Roku (built into TV) and the receiver is still giving me the sound from my DIrectv. How do I get the sound to go to my receiver?
Make sure the HDMI cable is attached to the ARC port on the TV as well as the AVR. I think you are saying it is, but make sure. I can't speak to Denon, but it's possible that ARC isn't enabled in your AVR. Also, some AVRs have two HDMI out ports, and only one is ARC enabled. Again, I don't know what you have but just some things to check. I don't use ARC on my two Roku TVs, so can't say for sure where any settings might be in there for enabling ARC.

Try this. I had the same problem and these steps fixed it.
