I am having issues with some audio, particularly in games, when my TV is set to 4k@60Hz resolution. I mentioned this in the massive flickering thread and cvare told me to break it out, even though I think this is all related.
Setup: NUC7I5BNH, Vizio m55-C2 4k TV, Audio either through TV or using ARC to Sony XT:HT1 soundbar.
Problem: When I have the resolution set to 4k@60Hz, ifI start a game in full screen mode that is at a different resolution than the desktop, I get no sound. If Windows resolution is set to 1080p in the Intel Graphics Settings, the sound is fine (but I don't want to change settings and reboot every time I want to pay a game). In one of the games, I can select windowed mode and the sound then works. However, when my resolution is set to 4k, it only displays in 1/4 of the screen so there is obviously another problem there. From looking around online, it sounds like others have experienced this before and it might be an HDMI handshake issue or some problem caused when trying to switch to a different resolution.
Games: LEGO Star Wars: The Complete Saga
LEGO Star Wars III: The Clone Wars
LEGO Star Wars: The Force Awakens (this is the one that the audio works in windowed mode but the video is weird)
The LEGO Movie Videogame
So the symptoms are different than with the flickering issues, but it all seems related to HDMI/driver issues. Is this a problem with the LSPCON chips in these NUCs?
DougArcher: Thank you very much for contacting the Intel® NUC communities. We are sorry to hear the NUC is not working as expected.
In order to try to fix this problem, please install driver version 4771:
If you already have that driver version installed, then we can try driver 4678:
Any further questions, please let me know.
Your response helped me realize that I had put the bit about the drivers I was using in the *other* thread and forgot to mention that here.
I tried 4771_BN and 4664. All of the games except for the Force Awakens work on 4664 BUT that is only because I am running at 1080p because 4k@60Hz is unusable on my computer if I'm not running the 4771_BN driver. This is why I think this is all related to the same problem that you guys haven't been able to address for months and, in my mind, makes it seem more like a hardware problem.
So testing 4678 won't really give any more new information because it's almost impossible to use the computer for anything when at 4k@60Hz. I can try and see if I can get the games to run, but do you understand what I'm saying? I'm stuck on one driver to solve the flickering issue (4771_BN) but that driver causes audio issues when games use a different native resolution when they are started. Make sense?
DougArcher: Thank you very much for letting us know those results. Yes, it makes sense, that is why we will do further research on this matter in order to try to find a possible solution. As soon as I get any updates, I will post all the details on this thread.
Any questions, please let me know.
I just wanted to let you know that currently Intel is working on this matter in order to try to find a possible fix for this problem.
DougArcher: In the meantime, please try to install driver version 4678 to try t o fix this issue:
Any questions, please let me know.
DougArcher: I just wanted to check if you were able to install the driver provided previously and if the problem persists after that?
Any questions, please let me know.
Can you please try the following driver and report your findings back?

When I try to install the 15.47 driver (4815), the installation fails and says: "The driver being installed is not validated for this computer" and won't continue the installation.
edit: I was able to manually install new audio drivers in the 4815 zip file and the problem still remains. If the display resolution is set to 4k@60Hz, the audio on the games I listed (and I'm assuming other programs that go fullscreen and change the resolution) doesn't work.
I have been researching on this issue and it may be a regression bug, since it was working fine on 15.45.4678 and got broken on later versions.
Can you please try this driver?
My apologies for the multiple requests.
Ok, I finally had time to work on this again. With the newest graphics driver installed (4849_BN) the sound doesn't work on applications that go to a lower resolution at full screen (1920 x 1080 for example). I then uninstalled the audio driver and installed the 4678 graphics driver and it still didn't work. So it does not actually work on the 4678 driver. Is there somewhere else I should file a bug report or any other log files to look at or upload? I really would like to be able to run at 4k and have audio that works.
We are currently investigating your report, in the meantime can you please provide me with the Intel® System Support Utility report? Here is the URL, https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- once you have it, you can attach it to the community post.
On the other hand and this maybe silly but after reading similar issues on Internet (not only on Intel platforms) can you look at your audio settings and make sure the device you want to use to output the audio is marked as default? It seems that it could be possible that Windows switches to a different audio device when it changes the resolution.
There is also a newer driver available here: https://downloadcenter.intel.com/download/27355/Graphics-Intel-Graphics-Driver-for-Windows-15-60-?pr... Download Intel® Graphics Driver for Windows* [15.60] version 15.60.01.4877 - in case you want to try it but I am thinking this may be more of a Windows issue than a driver problem.
SSU reports are attached, both before and after installing the audio driver from the 4877 graphics package. And I checked again and Intel Display Audio is definitely selected as the default audio device. I even disabled the other audio device and it still didn't work. If I plug directly into the front panel audio jack and use the Realtek audio output, the sound works fine, which is what makes me think this is an issue with the Intel Display Audio driver, not just a windows issue. Also, cvare was able to duplicate this issue so it's not just confined to my machine. As I mentioned to him, it seems like something is wrong with your driver, perhaps related to the LSPCON implementation of HDMI, and it's causing issues for me and a number of other people. The amount of time I've spent troubleshooting this issue with you guys is ridiculous. If @cvare can replicate the problem, I'd suggest you guys do the troubleshooting yourselves rather than continuing to use customers as QA. Sorry, just really frustrated with how many hours I've spent working on the most fundamental parts of this pc: video and audio.
