Continuing: Limited DD 5.1 with Amazon Video
Whatever is going on with Amazon Video + Fire TV delivering default stereo audio on titles known to have DD 5.1 available, is not yet resolved.
This issue has proven to be server side, but added to that is a requirement (in some cases) to perform a fix to the Fire TV (detailed here: Amazon Fire TV forum, find link in previous post, if required).
And, this fix is not straightforward. The procedure (in my case) had to include _all_ optional steps, and be repeated.
So... believing that the issue was resolved, I started a trial subscription to Starz. Immediately, I find that their featured series "Outlander" is streamed with basic stereo: no Dolby, whatsoever.
Next title tried was "Ant-Man": also, only basic stereo. And, the Closed Captions/subtitles were displayed 4 seconds after the spoken audio.
Not until I streamed "Into the Woods", did I receive DD 5.1. And the subtitles were spot-on. This movie is from the same distributor as "Ant-Man", Disney Digital.
Contacted Starz. Got this response: "Hello, Thank you for taking the time to contact us. We did check the titles that you mentioned and we did send those over with surround on, so your DD 5.1 should be supported. Our team is going to reach out to Amazon regarding this issue, but I would also suggest you contact Amazon as one of their customers to let them know you are having this issue. Thank you for making us aware of this. Please let me know if there is anything else that I can assist you with. Regards, Denice"
I did contact Amazon. It is always as last resort, and just to follow protocol. The answer I received from "Raj" said "I don't understand your question", followed by the usual mal-working link to yet another (blank/generic) web-form. Filled out and sent, again.
Other than users that populate these forums, I'm coming to accept that Amazon is right in considering "surround sound" to be low priority. Probably moved to no priority, as of now. Perhaps today's audience for streaming generally uses headphones? Or, most really don't notice any difference in the audio format, as long as the picture is good?
Consider that for at least 3 weeks, people have been buying streamed content, and/or using premium add-on services (Starz, Showtime, etc.), with Amazon Video to the Fire TV... and only some(?) users have noticed the lack of surround sound, and a handful have posted to forums.
I'll keep at this issue. But it is ironic to view a headline about Dolby + Amazon promoting "Dolby Vision" through Amazon Video... while 15+ year old DD 5.1 continues to break without much comment.
