Hi, i'm just gonna share my experience i had here with kodi (I also have used linux, with same experience)
i'm not gonna report this as an error or nothing because I have tried before send log and reports about this, and this can simply be due to bad hardware support for intel cpu/gpu gen 12, both on Linux and Windows, so Kodi won't be able to do its work as I know it can with different hardware. 
My english is not that great but I'm gonna try to share my experience as best I can.
To start with audio system i have:

Amplifier:
Denon AVC-A110

Speaker setup:
7.6.2

PC:
hardware:
ASRock H670M-ITX/ax with and Intel Core i5-12500 CPU
8GB ram

The problem started under linux where I experienced sound drop when playing movies with 4k resolution, TrueHD with atmos content. This was better under the Windows system, but did experience some drop, but not so much that it was impossible to watch movies.
Then after some research here on forums I stumbled over another one that had some similar issue on (https://forum.kodi.tv/showthread.php?tid=372242)
So after setting my Amplifier to standard the sound drop issue reduced a lot on linux too, but the problem is still there. I do experience a drop of sound in a specific place on a movie on linux, and then when i go in windows, that sound drop can happen in a bit different place. The drop is shorter in windows then linux.

And now to the issue i experienced:
When you have a passthrough set, the sound should travel untouched to the amplifier, and the amplifier should take care of this.
But what I experience is that the sound seems like it is going through a filter, the channel separations seem narrowed.

When I started the same film in Plex on the Windows system, the sound cuts were gone and the channel separation was superior when compared to kodi on both linux and windows systems.

my recommendation regarding this motherboard. Don't buy it if you intend to use it for kodi. It has every problem from day one.. Find another motherboard.

Thanks for your recommendation, a worthy note is that you're using onboard gfx, one wonders if that is at issue, and a gfx card might be the solve?

As far as Plex working better, suggest you try software rendering and see if that does anything for you. A lot of issues can come from the media itself, especially if you're relying on software decoding at source. Having drops in mid play on pass-through is definitely not expected behaviour, might want to try some music and see if the AVR set-up might be involved, if it's only vidoes than at least you can eliminate that as source. Keep the keyboard OSD monitors up to see if there's threshold or fetch issues. Looking at the URL link you left (I'm not a Linux specialist) but seems I got 'especially in motion scenes, little drops / cuts / breaks' from that would appears to be speed threshold.. and recommendation was this.

If you want to carry this further, throw us a bone with a proper debug log posted to a public paste-bin and link that URL with this thread.

Hi, let me try to explain abit here. (i did know about the changin on the denon to standard, I did refference to that same tread)

I have done comparing, and did it with a different hardware, did borrow a nvidia shield from a friend of mine. Did some run on my mainboard, and did compare with nvidia shield.
the channal seperations was much better, all detail did come much better from eath speakers, then with the mainboard. 
Kodi did work much better on Nvidia shield, and the detail on the sound was superiour. 
Ill know the driver for the mainboard is not at its best yet, but that day will one day arrive, untill then I will use different hardware, becaus expencive amplifyer deserve a source that can do its work perfekt.

Keep up the good work, kodi is awesome.

I have to say, the solutions to This sound drops, and bad Chanel separasjons. Was to install graphical card on the main board, and all the problem went away, both in linux, and windows.  No more sound drop at all on any kind, and the sound pictures is more wide and how it should be.. Seems lik the graphical card does thing right


The graphic card i went for was ASRock intel ARC A310..

So now if anyone else experience that the sound seems abit narrowed down, and experience sound sound drops you could try that out. 

Seems abit like that intel cpu with intigrated GPU can on some mainboard be a pain...

Long time passing for this hardware solve...

Thread marked solved.
