NUC (Hades Canyon) audio ports causing speaker humming or static noise (but not with headphones)

I just got the Hades Canyon NUC8i7HVK. Installed Windows 10 Pro 64-bit and most of the NUC drivers. Unfortunately, it seems that I'm getting a lot of static sound from my speakers, Harman/Kardon Soundsticks II which I have connected to the rear 3.5mm/optical audio port. I used these speakers with my previous computer, iMac, and they never emitted any static noise whatsoever.

 

What I've tried out

  • made sure I have the latest Realtek High Definition audio driver (NUC support page/downloads)
  • tested the front audio port -> static noise again
  • tested the rear port with headphones -> no static noise
  • tested the speakers when the NUC is switched off -> no static noise
  • tested to move the NUC power brick away from the Harman/Kardon subwoofer which doubles as the speaker amp -> static noise again

 

One interesting characteristic of this static noise is that when I do something like scroll with the mouse, it clearly affects the static noise.

 

As the headphones I tried out didn't emit any static noise, I would imagine the issue isn't with the audio port. I also suspected the power brick causing the static noise because of its proximity to the sub/amp but moving them apart didn't make any difference. I've read people having faulty power bricks that cause this but unfortunately I've no way to determine this.

 

Help!

  1. Please check the noise from speaker after disconnecting all devices from USB port.
  2. Please check the noise, after installing some shield on loudspeaker cable connected to the rear port.

Thank you for your advice. I did check the noise after disconnecting all USB devices but it did not make any difference. I also made sure the speaker connections were solid and even tried to plug the speaker to a different power outlet. The noise did not go away. Finally, I tested another audio plug from speakers to NUC's audio port but...you guessed it, noise.

 

I did find an acceptable compromise, though. As the powered speakers have their own volume control, I turned their volume down to a point that I can barely make out the noise. Then I turned the system volume all the way up so that the overall volume level would be acceptably loud. Don't get me wrong, the noise was not caused by the speakers' volume turned too high (I'd say they were at about 50% and I took them down to 25% to get minimal noise).

 

I guess these NUCs do not use as good audio components as Macs do (as I got no noise and especially no audio interference with iMac even when I turned the speakers all the way up). It's weird though that headphones (tested these with the same cable as I tested the speakers) did not pick up any noise/audio interference.

Found a workaround. I just received my new monitor (Dell S2719DC) which has an audio port. Connected the speakers to the monitor instead of the NUC. No static noise, no audio interference. I'm not saying that the audio ports on the NUC are bad (they certainly do work with my headphones without any issues) but I guess my Soundsticks and this NUC didn't have the right chemistry.

I'm new here so I cannot post a new thread.

 

Audio FIX for Hades Canyon NUC - "Audio Renderer Error" and other related issues.

 

I’ve been having major Audio problems with the Intel (Hades Canyon) Mini PC (NUC8I7HVK) but after trying this it’s FIXED.

 

The Latest Realtek audio drivers are seriously broken with intel on this unit, install older version driver 6.0.1.8323 and not 6.0.1.8454 .

This will fix the YouTube audio renderer error that crashes video every 10+ seconds as well as other video playback crashes.

The 6.0.1.8454 Driver breaks the Hades Canyon audio in YouTube and basically all other audio functionality including media players.

It appears to work at times when freshly installed but upon reboot it is immediately broken 15 seconds into a YouTube video.

 

The fix is to simply install the old version 6.0.1.8323 .

 

What is interesting is that online photos show a Realtek ALC700 is inside the Hades Canyon but this driver link doesn't even mention supporting it.

It is rather unfortunate that the "Intel Driver Support Assistant (DSA)" installs this bad driver as the latest driver, as I cannot imagine how many people are having this issue.

 

Probable relevant models - NUC8i7HVK - Intel® NUC Kit, NUC8i7HNKQC, NUC8i7HVKVA, NUC8i7HVKVAW, NUC8i7HNK.

Hello @MrCyberdude​ 

  1. I don't understand why you can open new thread? All members (even the new members) may open threads.
  2. More important, your message is an false alarm.
  3. I have NUC8i7HVK running the latest drivers and have no problems with video and audio. No problem in HG and neither in 4K.
  4. The Intel Graphic driver I have is version 25.20.100.6444 https://downloadcenter.intel.com/download/28438/Intel-HD-Graphics-Driver-for-Windows-10-64-bit-for-I...
  5. The AMD Radeon Driver version 20.20.11026.2001 https://downloadcenter.intel.com/download/28194/Radeon-RX-Vega-M-Graphics-Driver-for-Windows-10-64-b...

My first post, said I couldn’t post.

 

I spent days finding what was crashing the audio and it was reproduced over and over.

 

There are 3 audio drivers for the intel hades Canyon.

 

AMD

IntelHD

Realtek (ALC700)

 

the realtek driver is the issue.

 

Download each driver and extract the contents, they don’t even look similar and you cannot run a setup file from the extracted files.

 

installing them manually showed it changed it same crashing audio.

 

install the old and all is working.

Hello @MrCyberdude​ 

  1. In my NUC8i7HVK I have my speakers connected to Audio socket on my Dell monitor. The audio source in my case is from DP output (i.e. Graphic Drivers).
  2. In order to check the Realtek Audio Driver, I've connected my speakers to front Audio socket on my NUC.
  3. I've downloaded and installed the latest Audio Driver from Intel's site (ver. 6.0.1.8454): https://downloadcenter.intel.com/download/27879/Realtek-High-Definition-Audio-Driver-for-Windows-10-... . The installation was without any problems.
  4. After rebooting my NUC, I've checked video and audio, running video from YouTube (HD and 4K).
  5. I've have not detected any problems.
  6. I have Windows 10 Home version 1806, OS build 17763.316.

I'm glad you have no problems, unfortunately I purchased https://www.scorptec.com.au/product/Branded-Systems/NUC-&-Mini-PC/71990-BOXNUC8I7HVK4 and have had the audio issue present with the constant youtube error, this was repeatable back and forth between the 2 driver version installs.

Fairly sure I had windows10 version 1809 installed at the time.

Try the front audio port. I am getting feedback that sounds like the noise from inside the nuc through the back audio port. Put your ear close to the Nuc unit you can hear it operating, sounds like noise from the nvme ssd drive. I have a laptop that makes the same sound when processing data.

Hello @SStor5​ 

You are hearing noise from the Cooling Fan (which is normal), rather than fro the Solid State Drive. The SSD has no moving parts. 😄 When processing data more CPU power is required, therefore more heat is generated and therefore Cooling Fan increases RPM.

There are capacitors and inductors in nvme and ssds that in fact make high frequency noise.

I noticed that, when I play games (GPU usage 100%), the noise becomes louder. I guess the noise is related to GPU activities.

Finally I solved it by connecting my speaker to the monitor. The monitor is connected to my NUC with an HDMI cable.
