Roku Streaming Stick not working with ARC/AVR unless power is reset
I have a Roku 4k streaming stick connected to a Hisense TV, which is connected via HDMI/ARC to a Denon receiver. If all three turn on at the same time, the Roku will only play sound through the TV, not the receiver. In order to fix that, I have to turn on the TV and receiver first, wait for them to load, then plug in the Roku. After that, it works fine. If the Roku falls asleep due to inactivity, it reverts to the TV speakers and I have to restart this whole process.
I’ve tried every TV HDMI port and with or without the USB power with no change. I swapped the Roku stick out for a Google TV dongle and it worked without any problem, so the issue is limited to the Roku stick. This started right out of the box.
Sorry, I missed the part where you said that you tried it with and without the USB power adapter. Does your stick have the "power saving" option under Settings->System->Power? Some Roku devices do and some don't.
