Same here across all my Roku devices, Premier, stick, and freaking Ultra. This volume problem has become unacceptable for daily watching. Same old story, volume decreases until unintelligible and you have to stop and rewind a second or two to get back to normal volume. I'm not sure why you guys are ignoring this, but unless it's addressed soon, Roku is out the door in my house. Well, at least the rest of them. I replaced the Ultra with an Apple TV, problem solved. Make no mistake, my previous recommendations to friends have turned into a hard NO.
