Will the progress bar/duration timer ‘jumping’ issue when playing Atmos music (audio only) via HDMI pass-through be fixed in 19.3?

Kodi 19.3 seems to have improved the dropout problem with high bitrate Dolby TrueHD. The train scene in Zootopia is now working where it once dropped out.(the geezers firing out steam in the snow)
However during that same scene it is now dropping out in places where it did not previously. Only a couple of occasions and much more subtle. It is a vast improvement but still not perfect.

Actually i am on LE master now (self build) and have tried your mentioned build also to check, if my build has issues. Situation is still the same.
First i did think my equipment (HDMI cable, AVR etc) has an issue when using passthrough, but when i disable PT and let kodi decode audio audio to MultiCH PCM drop outs are more worse, so i am pretty sure somethink else is broken.
I have written it already in the other thread, i do not have frame drops during audio drops. Overall i have no frame drops. CPU usage is not too high. Framerate switching is on and suitable for the source -> 24p Source -> 24p TV.
I have no clue what i can check more.
Who has no audio drops and with similar system ? Intel j4125, 8 GB Ram, 32 GB SSD. 1gb Ethernet.
As i have written earlier, i have also audio issues with zootopia regardless if i have played it from local ssd or nfs mount.

I am still trying around to fix the issue on my box.
I have experienced following situation: as latest LE Master has some issues regarding to fetch the right audio card (i have also one usb box for ananlogue only) sometimes the Audio output is decoding the TrueHD to that box. 2ch only. but no drop out at all.
An older Movie with DTS-HD Master no drop out.
The True HD amaze demo, no drop out.
Newer DTS-HD Master (Bad boys II ) sometimes few seconds no audio
Invisible man True-HD, drop outs
Zootoopia , drop outs (i saw high bitrate, up to 10mbit)
And HDMI MCH-Output has also drop outs.
When switching same movie to DD+, if available, no drop outs.
But especially Bad Boys given me maybe a hint. Sometimes Audio disapear completly and it was enough to switch the audio mode on the AVR to get Audio back.
My feeling is, that the audio hdmi link is lost and i have to look to the cable. It is a HDMI high speed 2.0. But not certified and already > 3 years old. Advertised as 18 Gbs. Class. Other cables i have tried are not newer or better.
Especially why the 2ch decoding with usb box giving me complete no drop out. It seems always, when i comes to higher audio bandwidh usage over HDMI i have issues. AVR is showing me no link lost. Picture has no issues.
I have now ordered a certified HDMI 2.1 48gbs cable an will give an update.

Since the Nvidia Shield update to Android 11 recently, I no longer have any playback issues on my Shield with KODI (other than the built-in ProjectM still causes audio skips here and there when it changes visuals, but the separate app version works perfectly with it and has better controls and quality so I simply activate it instead when I want ProjectM visuals and it can control the tracks from it as well). No Atmos playback glitches anymore on any of the ones I had an issue with with higher bit-rates (e.g. INXS' album KICK in Atmos). No more Asus router issues oddly stopping playback either (that was a big problem for almost two years now; I was about ready to buy a different router). The OS update seemed to solve nearly everything and the 19.3 update fixed the rest. The only thing Atmos doesn't work on now on the 2017 Pro model is Netflix (but the KODI Plugin version does work in Atmos, although I'm not crazy about its GUI interface). The picture viewer has crashed a few times, though come to think of it, but that's it. This is the smoothest operating playback has been with KODI since I got the Shield over four years ago.
