I have a 7i3BNH. All drivers appear to be current but there is no 7.1/5.1 output and I don't see any configuration for this in device manager. Under audio/video inputs and outputs my options are Maranzt -AVR(Intel(R) Diplay Audio, Microphone (Realtek High Definition Audio SST) and Stereo Mix (Realtek High Definition Audio SST.) I was previously using various Minix Android boxes and my Marantz receiver always detected Dolby Digital and DTS coding from them. Any help appreciated.
Thank you for joining the Intel® NUC community. My apologies for the inconvenience.
I would like to gather more information regarding your Intel® NUC in order to address this matter in the most accurate way, please provide your https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- Download Intel® System Support Utility for Windows* report. In the meantime, I would like to know if you have followed our Surround Sound Setup Guide for NUC, you can find it here: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/Configure-Surround-Sound.pdf https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/Configure-Surround-Sound.pdf

Did anything abnormal show up in the Utilities for Windows report? I'm running the HDMI cable out from the Nuk to an HDMI input of my receiver. From there I use the HDMI out of the receiver to an HDMI input of the TV. Even using the recommended media player from your first reply it still displays stereo on the receiver. Just for testing purposes I reconnected my Minix media player and was able to get a Dolby Digital and DTS signal.
I would inmediatelly recommend you a couple of updates for your system:
Latest BIOS version 50:
Graphics Driver version 4664, it is not latest but most stable:
...and most important, HDMI 2.0 firmware update
I see that you have a Maranzt -AVR, and if this is the networked model it comes with HDMI 2.0a, I hope this firmware resolves the issue you have with Audio.
See below the specific Audio technologies supported: https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i3BN_TechProdSpec.pdf https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC7i3BN_TechProdSpec.pdf
I hope this helps,
Well it seems to depend on what I'm using as far as a player if I get multichannel audio or not. If I use Kodi or Plex I can get Dolby TrueHD / DTS-HD or multichannel IN depending on how it's configured. If I use 5k player then only stereo but the best picture quality. VLC gives me multichannel IN but the audio is very low. The 321 player you suggested only gives me stereo. I also realized my preamp only passed HDMI 1.4a and not 2.0. So I'm running the NUC HDMI cable straight to my television and I'm running the NUC USB-C output via HDMI adapter to my preamp for audio. So all in all it's working pretty good and I'm pleased. Thanks for your help and sorry for the delayed response.
