Remotes

[RedSparrow]

Is there a published or user findings to confirm which devices private listening will work for on the RC03 remote?  

I have a couple RC03 remotes that I'd like to use for when we take Roku on vacation.  Unable to get sound from a 3920RW which I typically carry with us.  The remote can be paired, headphone icon/volume control shows up on screen when headphones plugged in, but no sound.  

Thanks and happy streaming.
