I have NUC 11 PAHi7.
I have that connected to a Samsung QN95A TV.
To the Samsung QN95A I have Sonos Arc connected on the (e)ARC HDMI input.
It is set to eARC.
The Sonos Arc supports TrueHD & TrueHD Atmos.
The QN95A support TrueHD & TrueHD Atmos when using Passthrough (which I am using).
I am running Windows 10 - fully updated, including most recent drivers.
TrueHD Audio is not working.
I tested different applications to test/play files with TrueHD audio in it - in none it works.
Among the tested applications are Kodi & VLC.
This is a problem mostly while trying to play movies that have TrueHD Atmos audio.
Atmos in Dolby Digital is working btw, like DD and DDP5.1.
Just not TrueHD.
This is a known issue - see:
I was waiting for the latest BIOS update to fix this. Today BIOS 046 got released.
I tested a few TrueHD files, but none of them work - i.e. no audio.
Please fix this - TrueHD Atmos is a very frequently used format.
Attached my SSU.
Thank you for posting on the Intel® communities.

Did you purchase the HEVC codec needed to play the videos: https://apps.microsoft.com/store/detail/hevc-video-extensions/9NMZLZ57R3T7?hl=en-us&gl=US?
Let me do some testing and I'll get back to you.
I am using Kodi and VLC to play the files - they contain their own codecs, so I wouldn't need the HEVC purchase from the MS Store. But, as a test I did spent the 1 EUR to buy it and test, but it didn't make a difference.
In this thread:
There was new information that you had to flash the latest BIOS 2x for the HDMI fix to apply. I applied it a whole bunch of times now in a row, but unfortunately that didn't fix it for me.
If there is a way to check the HDMI firmware level I can check if it got updated or not - but not sure how.
Some small additional info: when I look in Windows at the monitor (which is the QN95A TV) it shows supported audio formats, and Dolby TrueHD is displayed there as being supported. But, it just doesn't work.
Thank you for testing the HEVC codec.
I did some testing over the weekend and while I don't have your setup, I do have a home theater setup consisting of a Denon AV receiver and surround speakers, so I can definitely test if Dolby TrueHD is working, which as you can see in the attached video, it is.

Just in case somebody else looks at this thread in the future: we were never able to fix this issue with the now 'old' NUC11PAHi7.
BIOS updates and trying USB-C to connect to my TV - it all didn't matter.
Eventually we exchanged the NUC11 with the new model - NUC11PAHi70Z. That one worked out of the box.
