Solving playback issues

[kaisemic]

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.

If you're using the TV's USB port to power the stick, try using the supplied USB power adapter plugged into the wall.  Also, if there's a "power saving" option under Settings->System->Power, try disabling it.

I appreciate the suggestion. I’ve tried with and without the power adapter but the end result is the same.

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.
