True I read the same procedure on ROku's tech support. The issue I have is that this procedure seems as placebo to make people think they actually thought about it.
I learned something new today. My original issue was/is that when I am trying to rent an Atmos movie in HDR using Vudu, the sound comes "hidden" within DDS+, the receiver actually says DDS+ but chirps, buffers and pops to the point the movie stops playing.
But today I tried something different, I bought a movie in Vudu in atmos and not only played flawlessly but the receiver actually displayed "atmos" on its display.
Now I am thinking that it might be Vudu and not Roku.... still very confused but it worked.
thanks
In that case it may not be your particular problem. It's a known issue with ROKU devices and if HDMI handshaking was the source of your problem, it's a known remedy.
I'm only posting this because it may help others with a ROKU audio dropout issue. It would be unfortunate if others didn't try it; it's easy enough to confirm and only takes a few moments to try.
