same problem here kind of.
Box is m8s pro l.
Internal nexus ATV.
SD libreelec.
Libreelec
Passthrough enabled,
Av Receiver connected thru hdmi is picking up 7.1 PCM regardless of source.
Av Receiver detects 7.1 PCM For all speaker configurations apart from 2.0.
When 2.0 is selected, AV Receiver detects 2.0 PCM.
1080p 24p works correctly.
Nexus ATV.
Hdmi Passthrough works correctly.
1080p24hz doesn't work correctly.
Apart from the above, libreelec is mint!
Thanks to kszaq
For audio passthrough you have to disable Settings->Player->Videos->Sync playback to display.
If you enable this option all multichanel audio is decoded to Multichannel PCM. SPDIF is capable only stereo PCM.
Thx, but it is disabled by default and was disabled on all devices I've tested it on. Is it possible that it's that specific box model issue?
Last post on the above suggests turning off hardware acceleration. I'll try that later.
HW acceleration of video? That way it will be unplayable

No.
Passthrough works if 'sync playback to display' is disabled.
Checked on my S912

It is disabled. All I'm getting is 7.1 PCM.

I've referred to "Last post on the above suggests turning off hardware acceleration. I'll try that later."
As mentioned before, I have "sync playback to display" disabled. It is disabled by default and I've double checked. I don't have such issue on any other device so this makes me think that maybe H96 Pro+ or at least some batches have it incorrect in hardware/firmware?
Can anyone please point me in the direction of a file to get the remote on the KM8 Pro working?

I don´t believe incorrect hardware - what´s about botchy installation/configuration ?
Did You try a fresh installation without addons, skins etc. ?

Tim, I'm not the only one that have such issues with this specific model + I've configured other 3 devices the same way and only that one has problems in both Android and LibreElec. Kodi forums mention that some boxes don't have "proper IEC Passthrough Audio support".
I've tried fresh installation on latest build (8.2.2.3) and Alpha (8.90.1.1)

Helpful!
What's your setup Tim?
Kodi forums mention that some boxes don't have "proper IEC Passthrough Audio support".
Could be U-Boot issue - must be solved by manufacturer
What's your setup Tim?
Did no special setup - only enabled passthrough
And we all know it won't be done 
I'll just return it. Do you know if Neo U9-H or other (less expensive than U9) box with S912 have this working?
AFAIK neo U9 works - but You have to use a customized dtb file
I own a vorke z6 - working oob - only the front display is working in android only - I taped it

Had xbmc/kodi on a win htpc since 09
Outputting 1080p24hz to my plasma and passing through via optical to a Sony 5.1 av amp. All worked fine.
Now have libreelec on the S912 based m8s pro l connected via hdmi to an onkyo av amp through to the same plasma.
1080p24hz is working fine. Pass through is not.
Av amp is only picking up 7.1 PCM.
I guess I'll give U9 a try as those less known brand products seem to be hit-and-miss.

U9 is expensive.
Whats about a S905X box ?
My daily boxes are S905X, Amazon Fire and soon Apple TV 4k. I bought my S912 just for playing around
