will do more testing and permutations (new cable, different optical port on the receiver etc.) over the next few days
I can't do the test that you described because my TV only outputs DD5.1 over optical if it is acting as the tuner over the air as the source; it will not pass DD5.1 into the optical out port if it originates from an input source into the display/panel otherwise.
So I just got my Ultra configured...I like it a lot...transcoding is working fine...DD 5.1 over optical for all streams. Good to be back with Roku!
Are you getting any snapping/static sounds when a DD 5.1 stream first starts on your AVR as Dodgersfan reported? What kind of AVR do you have?
It's a miracle! :lol: I just got my Ultra and have it up and yes it does transcode Dolby Plus to Standard over optical. After all these years I never thought it would happen, especially after the dissapointment of the Roku 4 last year. DD working on Netflix and Amazon and a surprise, Digtial Pro-logic on SlingTV. This is a big surprise. I've been a subscriber recently and my Amazon Fire Tv did not produce a digtial sound from Sling. Don't know if any Sling movies are in full Dolby Digital yet. When bought at Walmart you get 2 months of Sling free.
I am not getting any strange noises when opening a stream on my system. I have a 15 year Rotel system with separate processor and power amp. Of course, are are no HDMI connections. My optical cable is one from Amazon that cost about 10.00.
