Intel UHD Graphics: 184.108.40.20680
Intel Display Audio: 10.27.0.9
Nuc is connected via HDMI to Denon 3500H AVR
Music has been played through Roon, MusicBee, and VLC player to test.
WASAPI mode is being used.
I am not able to play any multichannel audio (5 ch, 5.1) which is not 48 or 96 kHz (44.1, 88.2 don't work). I have tested many sample rates for stereo files (44.1, 48, 88.2, 96, 192) and all work.
If I change to use directsound (in musicbee application) the audio is passed through based on the speaker config in windows and all sample rates work; however, this doesn't work in WASAPI mode.
In WASAPI mode if I resample to 48 or 96 kHz it will then work and audio will be passed through. But my AVR supports all the other sample rates and so I'm unclear why only these two sample rates work in WASAPI.
Thank you for posting on the Intel® communities.
In order to check this behavior further could you please provide the following information?
1- How many Intel® NUCs do you have that are affected by this issue?
2- By any chance are you able to test the audio output without the AVR? What is the behavior?
3- Does the issue persist with different media players? if yes, please provide details.
4- Have you tested this configuration with different devices? For instance, another AVR or a different Intel® NUC.
5- Please provide steps to reproduce this and kindly elaborate more on how you are connecting the devices, cable types, etc. If possible, please include screenshots or a short video.
Also, please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread to gather more details about your system.
1- Download the Intel® SSU and save the application on your computer.
2- Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
3- To save your scan, click Next and click Save.
To attach a file, you must click the “Attach” option on the bottom left-hand corner of the response box.

We are currently looking into this issue as we are trying to replicate your report but this may take some extra time during the current pandemic situation, I apologize for the inconvenience and will keep you posted on any progress we make.
We have been doing some testing but I believe the best way to approach your report is by trying the audio files that you are having trouble with. Can you please provide me with some sample files and any necessary details to replicate this issue?
Please let me know if you still need assistance with this issue, if you do, please provide with all necessary details to be able to duplicate.
I would need to understand how the devices are connected (input/output), the software that you are using, and any setting we need to be aware of.
