I'm running a Windows 10 Pro VM on UnRaid 6.7 0 RC5 and I'm experiencing occasional "demoic sound."  I'm passing thru my on-board sound card  (AMD Azalia (IntelHDA)) on my ASUS M5A97 R2.0 motherboard.  I've run the MS-Util utility recommended in Space Invader's video.  The demonic sound only occurs occasionally and I can usually correct it by opening and running sound the Windows sound configuration setup.  I'm also passing thru a video card (AMD Radeon HD 5000/6000) and a  Logitech mouse and keyboard  (unifying receiver.)  BTW, this issue existed in prior RCs and 6. stable release. Any thoughts?

Following. This would make sense if you were running 6.6.6 but alas... 😈

I should have seen that coming...😂

Low possibility, but you might try and add something like:

  <cputune>
    ...
    ...
    <emulatorpin cpuset='0,4'/>
  </cputune>

and edit the CPU's that QEMU gets to use, move them off the cores that the VM uses...  On my system UnRaid has to be on Core 0, and I also pass through its Hyperthreaded core as well...  Edit to line up with you system...

In addition to pinning the cores to my Windows VM, I isolated the cores, rebooted, so far, so good.  Hopefully I excised the demons!
