Open your own thread. Provide your Debug Log. I am not sure where you read uncertainty from the wiki.
Settings: 2.0 (!) no 2.1 no nothing -> 2 channels only
Passthrough: AC3 enabled and Dolby Transcoding enabled.

-> see you in your thread. From the log it is 100% clear why you see PCM on the AVR ... cause you configured kodi to do so.

Thanks again fritsch
The Wiki I looked at was https://kodi.wiki/view/HOW-TO:Submit_a_bug_report

As for selecting “Passthrough: AC3 enabled and Dolby Transcoding enabled”, (as shown in the illustration at https://kodi.wiki/view/Settings/System/Audio), I am unable to select Dolby Transcoding as it is missing from my menu.

Not sure whether this is the cause of my problem, or whether I should be making any other changes to my setup, but I have set up a new thread as per your advice.

Quick question, have the recommended shield and kodi settings been removed from the OP? Are they no longer needed? I'm on Omega Beta 3

Think you got the threads confused, and were perhaps looking for the old thread that was previously pinned at top:

Aaah there you go, thx!

This change probably caused this issue

https://github.com/xbmc/xbmc/issues/24950

it's audio related and caused sometime between beta2 and beta3.

Im sorry to bump this thread, but I think I have reason.

I have this issue on old firmware for Firestick 4k (6.2.7.1) because you need it for proper passthrough, and I believe I have encountered this issue. After some minutes, SOME movies get out of sync even 1080p etc when it never has for too many years too count. I applied the fix and am watching a movie that gets out of sync now, but didn't on 20.

I also actually have some questions:

The fix, on 20 and lower with firmware greater than 6.2.7.1, for 5.1 was to switch to the other packer and you would then get transcoded 5.1 that *sounded far worse* than the other packer, on 6.2.7.1. You could not get anything better than transcoded 5.1 as well; No DTS, DD+, Atmos... it just does not output audio.

Now, I guess this is where my question comes in... I noticed that Kodi 21 has a single packer, and a single passthrough option. I am not sure if this works well with my setup (5.1.2 Atmos, but usually just 5.1 + PL2z) as I am currently awaiting a new lease to start and am living at a hotel. Stuff in storage :-( so I cant test for myself.

Is this single packer, and single passthrough option, equivalent to the passthrough support before? Is it the same packer, or other packer in 21? If it is the "same" will it still sound worse like mentioned above? (had a more digitized sound and crossover seemed off)

Ill be able to test myself when I move mid september, and I will day one for sure... just wondering how this single packer\passthrough setup works compared to the old version?

*This did fix it, so if you are using a Fire Stick 4k, and maybe the other Fire devices on the old firmware which officially support DTS passthrough etc in 3rd party apps, you should create and make advancedsettings.xml and add those entries, probably always starting at 21 should your audio get out of sync at times.

Kodi still has both packers. That it only shows one of them rather means that the new HDMI hot plug code on startup is not working properly for you.

Make sure you use a v21 nightly build, it has that mitigated. It should show both: iec and raw.
