Sound Problems in macOS vm - Display-port Audio VEGA FE

I'm new at this, I succsfully able to bassthrought MY Vega FE card to macOS mojave 10.14.6, and I made sound working by pass-through the video device as multi functional and add the audio device as sub-function on the same bus/slot as showing here to work with macOS-vm:

<hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x84' slot='0x00' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x84' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x1' multifunction='on'/>
    </hostdev>

Now when I play music through display-port and even system sounds I get random micro cuts in the audio, static noises.

I searched about this I think it's the MSI problem, but how I can fix this with macOS vm.

Here's my XML for my VM:
