I've had a nuc 8i7HVK Hades Canyon nuc for a few weeks - and just got some new speakers which I plugged into the rear 3.5mm audio jack.
When the nuc isn't under load the speakers play music without noise (hissing / interference) fine. But when I play a game (Civilization 6), and the nuc is under load - all sorts of audio interference comes out of the speakers.
When I move the audio plug to the front 3.5mm jack - it works perfectly and the noise is gone.
Is this a design flaw? How can I fix this?
Thank you very much for contacting the Intel® Communities Team, niico. I will be more than happy to assist you.
In this case, please install the BIOS for your unit (0040). Click https://downloadmirror.intel.com/27808/eng/HN0040.bio here to download .bio file and use this guide to install it: https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html
In addition, install the latest Realtek* audio drivers (8323). Here is download link: https://downloadmirror.intel.com/27709/eng/Audio_Win10_64_18.104.22.16856.zip https://downloadmirror.intel.com/27709/eng/Audio_Win10_64_22.214.171.12456.zip
Regarding the audio drivers - you've linked to 126.96.36.19956 - the latest version listed on the driver download page is 188.8.131.5223.

Can you tell me why 8256 isn't listed on that page?
Am I looking in the wrong place? If this is the best driver why haven't they updated the above page with the link?
Are there any other updated drivers that, for whatever reason, aren't on that page either?
I just tested this with BIOS 040, and I can't hear any difference. No noise or other extraneous sounds coming from that back audio port.
Thanks for bringing this up. I hope 040 resolves the issue for you!
Have you tried any other speakers or headphones? Probably not any difference but worth checking. Also, did you install the latest Realtek Audio driver (184.108.40.20623)? I tried playing audio under load on my HVK with a clean install of Windows 10 RS4 (1803) and had no trouble with static on either back or front ports. Also, are you using Windows 10 RS3 (1709) or RS4 (1803). Did you install all the drivers manually or let Windows Update install drivers?
Thanks - strange there's no Express BIOS update .exe file. I'll try this update - was something in the BIOS specifically updated to address this issue?
Mike - note it only happens when the computer is under heavy load - eg in games.
The drivers that you see on a NUC's downloads page are those that have been validated with this NUC. It is possible that a newer driver has been released by Intel's graphics team but this driver may not as yet have been formally validated with the NUC.
Hope this helps,
Thanks a lot.
Whats the best way to go about getting the unvalidated drivers?
How do I know which ones are appropriate for my Nuc? (I realise there's some risk involved).
If you look specifically for a driver, rather than looking for the drivers for a particular NUC, then you should see the latest available driver that has been posted. Personally, I don't use a driver unless it is posted to the NUC's downloads page (edit: or I am specifically told to do so by Intel). From time to time, Windows Update sneaks in a newer one on me, however.
This may sound a bit random but bear with me. I had the same problem. Updating BIOS didn't appear to help, and neither did switching ports.
My power brick was close to the sub for my sound as well as the input cables. I moved the power brick away from the cabling and the sub, and the noise and feedback is now resolved.
Interesting - it didn't work for me and the fact the noiseyness only happens when plugged into the back port - not the front port - tells me there's a flaw here, and probably a hardware flaw.
Hopefully not and a future software update will fix this - but Intel - do you know about this?
Make sure you don't have a "ground loop" by ensuring your audio system and computer+monitor+perhiperhals are all plugged into the same power circuit.
I have high powered speakers (QSC K8), which I like to keep on their own circuit (cuz they draw quite a bit of juice), and so I use an optical connection (audio output from my monitor to speakers) to ensure electrical isolation (that I'm not creating a loop by connecting multiple circuits together).
Ensure they are on the same circuit.
When you plug things together such that there's two ways to get back to ground (via multiple circuits), you are essentially creating a loop, and magnetic fields within the equipment will induce a current in that loop, giving you noise.
With only a single circuit, there's only one way to ground, meaning no loop, and no noise.
https://en.wikipedia.org/wiki/Ground_loop_(electricity) Ground loop (electricity) - Wikipedia
FYI, I solved my ground loop by swapping out the original AC adapter (with 3-prong plug) for one from a notebook that uses a two prong plug. No ground connection = no current flowing across the ground. A while back I fixed a similar problem with an old Asus notebook in the same manner. The power adapter for the NUC -- at least for my NUC (a NUC7PJYH) is a 2.5mm center pin, 5.5mm barrel, center positive, and 19 volts DC.
Not sure if your high-end NUC would have this option or not... What's the power requirement for the Hades Canyon models, anyway?
Hahaha, well, now you've dragged my other thread into this:
It apparently uses some new form of alternating current that uses positive, negative, and sense conductors, or... something ;-)
