@WillFulmer We owe thanks to someone else in this forum! I'd tag them if I could remember who it was without scrolling... and I'm too lazy to do that. I must say while I'm VERY thankful for this forum, it would be even better if Roku would fix the problem and send out a software fix so people don't have to search online for this solution! That said, I'm glad it was resolved because I was sick and tired of restarting the **bleep** device every time I wanted to stream something using the Roku Ultra.
I am having the exact same problems with this new Roku Ultra. Samsung TV and Denon amplifier as well. I dropped my cable provider as well to go to this new system and it is awful. My problems occur with Netflix, Amazon, and the other paid providers. UTubeTV is working fine. None of it makes sense but my options are to return the Roku Ultra, and to have another service call from my audio visual company, which is very expensive. I give up.
My volume mode has been set to off since I got the Ultra. Problem just started when I went to play You-Tube. Been dropping out ever since. I tend to agree it is a hardware issue possibly caused by heat. Something is causing sync issues thru the hdmi output. Hope someone comes up with a practical fix or Apple TV it is!
I can;t get a menu to pop-up during playback mode. But really it doesn't matter. Roku Ultra has so many issues, it's hard to deal with it anymore. The sound issue that I originally had is almost all gone (I think because I took it off the AUTO mode and kept it on 1080 (or whatever) which really screws with the 4K pic...but whatever). Now the issue is when I start a program (like Netflix, etc...mostly happens with the crappiest of interfaces YouTube) I start the "show" and the Roku goes to a green screen (my wife would call it BLUE) where I need to press the HOME button, and restart the APP and navigate to the show again. AWFUL. And still Roku Customer Service is totally unresponsive!!!
