Unable to get multichannel audio

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.

Regards,

Dan

Thank you for joining the Intel® NUC community. My apologies for the inconvenience.

Hi,

I think the problem might be the inability to update the graphics card. And when I go to manage audio devices the 5.1/7.1 option is unavailable, only stereo. Requested attachment included. Thanks Amy.

/thread/117259 Madreefer, thank you for file.

Could you please describe the connection configuration? How is the Intel® NUC connected to the receiver?

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.

thx,

Dan

Question. How come when I go to "manage audio devices" the only option I'm given is stereo? I should have a 5.1/7.1 option, correct? Thanks for your help.

Hello Madreefer,

I would inmediatelly recommend you a couple of updates for your system:

Latest BIOS version 50:

https://downloadcenter.intel.com/download/27057/NUCs-BIOS-Update-BNKBL357-86A-?product=95066

Graphics Driver version 4664, it is not latest but most stable:

https://downloadcenter.intel.com/download/26975/Intel-HD-Graphics-Driver-for-Windows-10-for-Intel-NU...

...and most important, HDMI 2.0 firmware update

https://downloadcenter.intel.com/download/26609/NUCs-HDMI-2-0-Firmware-Update-Tool-for-Intel-NUC-Kit...

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,

Ronny G

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.
