TrueHD and DTS-HD on NUC8i5BE

[Dejbjaerg]

Hello,

I have a NUC8i5BEB. It is connected to a DENON X2700H AVR that drives a 5.2.2 ATMOS-setup. 

I can't figure out how to get the NUC to pass TrueHD and DTS-HD audio to the AVR. Dolby Digital Plus works fine. 

If I use a USB-C dock instead of the NUCs HDMI it works fine, TrueHD and GTX-HD is passing through to the AVR (however only in 4K 60 Hz).

Things I have tried:

- Fully updated the NUC, including BIOS. I've tried updating the HDMI firmware, but the software fails. Maybe the HDMI is fully updated with the BIOS update? 

- Serveral different players, including KODI and VLC. 

- Any different settings I can think of in Windows. Windows does list both TrueHD and DTX-HD as working in sound settings. 

- Different resolutions and refresh rates. 

- Every solution in other forums I can find.

What more can I try? As mentioned, everything works with a USB-C dock, but that's not long lasting solution. It worked without touching any of the settings with the dock.

Is it the HDMI-port in the NUC? I can find many forums where TrueHD and DTS-HD works on much older NUCs.

Hello Dejbjaerg,

Thank you for posting on the Intel® communities.  

To better assist you I would appreciate if you could provide the following information:

• Can you please confirm the BIOS version? Is it version 0085?
• Was this setup working fine at a certain point or is this the first time that you are testing it?
• What error message do you get while installing the HDMI firmware?

To gather more information about your system I would appreciate if you could run the following tool and attach the reports generated.

Hello Esteban

- The BIOS version is BECFL357.86A.0085.2020.1007.1917 , 07-10-2020 12:00

- The setup has never worked. I've only just got the AVR.

- This is the error I get when trying to update the HDMI firmware. I can't check current FW version either.

I have attached the scan from Intel SSU.

I have also tried a more simple USB-C to HDMI 2.0 adapter from HP, but that does not work either.

Hi Dejbjaerg,

Before we troubleshoot the TrueHD and DTS-HD issue that you are reporting, I would recommend resolving the HDMI FW update error that you are getting.

On your previous screenshot, I see that the FW update tool is not reporting the correct graphics adapter, your system is reading Intel when it should be recognizing: Intel (LS-PCON) can you try refreshing it and see if it picks up the correct one?

Thanks,

Ronny G

Hi

I've made a video of how the tool behaves. I can't get it to view anything other than 'Intel'.
