Hi Espen Grindvold, I am sorry for the behavior.
Let me ask you, does the issue happen with a local video or audio file? Can it also be tested without using the AVR?
the issue is the same with a local video or audio file.
If I connect the NUC to my TV, the stereo sound works just fine, both through the TV speakers and through optical output on the TV to the AVR. But since my TV cannot handle anything else than stereo sound, I'm not able to have surround with this setup.
Before I got the NUC I had the exact same setup, just with another computer, and I did not have any problems..
Edit: Was somehow able to isolate the problem. The sound does not disappear, but volume gets really low. For instance, I usually listen to music around -30 on my AVR, and when the problem occurs, I have to set the AVR to at least +15-20 to get any decent sound.
Anyway, I found a fix. By deleting the drivers for Intel® Display Audio and use standard Microsoft drivers, which installs after I reboot, everything works fine. The drivers are clearly not as good, since I get some noise from my speakers. At least it works.
I will keep myself updated if any new drivers comes out.

Please try updating the Intel® NUC BIOS and AVR firmware, and report if issue persists with Intel® driver.
Updating the BIOS did not help, and I'm back to the MS drivers. Sadly, my AVR's firmware is not upgradeable without any assistance from a workshop.
So, you should have had Intel® HD Graphics driver 10.18.10.3345 along with BIOS version 0022 before you went back to Microsoft*’s driver.
It should have been fixed based on this: https://communities.intel.com/message/218663#218663
We will take a look into it.
Is it possible to provide the dxdiag report when using Intel® HD Graphics driver?
(Windows* key + R, dxdiag, Save All Information)
Thanks, it has been forwarded to engineering.
