I have a new Ultra going into an Onkyo TX RZ 820 receiver via HDMI (from there to LG OLED TV)
Netflix, Showtime Anytime, HBO Go are all ok, but everything on Amazon is out of sync (audio ahead of video) by about a 1/4 of a second-- enough to make it unwatchable. I called Amazon, and they got a Roku tech person on the line. They had me re-register the device and re-install the Amazon app etc. No change.They also had me connect the Ultra directly to the TV and the problem went away. (they said ok, you can watch it that way!! I laughed and asked them if I should throw out my receiver and 5 speakers) BTW, cable box, and blu-ray player all OK.
I tried my old Roku 3 in the same input on the receiver and the problem goes away! (I never had any problems with my Roku 3 and my old Yamaha receiver)
I find it so strange that it works on everything except Amazon. And if the problem was the Onkyo, why does the Roku 3 work perfectly through it??
The ff/rw trick did not work for me! This is driving me crazy. At this point, Amazon is blaming Roku, and Roku is blaming Amazon. Although, perhaps Onkyo is the perpetrator. Right now I put my old Roku 3 in the system on another input and added the activity to my Harmony Elite remote. I feel like an idiot with two Roku's on my TV stand. And of course I can't watch any 4k on Amazon! Anybody have any more ideas?
