I was recently given the suggestion of installing unRAID 6 onto my workstation, which I have followed through with. In a few days, I intend to buy a basic license. However, I'd like to have a certain issue ironed out before then. I am currently getting the following error after attempting to pass 2 PCI (not PCI-e) sound cards through to the Windows 10 VM:

internal error: Unknown PCI header type '127'

 

From what I understand, however, that error is usually associated with video card passthrough. Here is my list of PCI devices (large image):

 

 

Here are the edits to the XML I have made thus far. I added the following:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x07' slot='0x04' function='0x0'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x07' slot='0x04' function='0x2'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x07' slot='0x0a' function='0x0'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x2'/>
      </source>
    </hostdev>

but was met with an error for device address 07:04.0 . So, I kicked it (along with its associated devices) from the XML. That was the first sound card that I removed. After doing so, I was left with this part of the edit in tact:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/>
      </source>
    </hostdev>
    
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x2'/>
      </source>
    </hostdev>

I then received the error mentioned above (PCI header type '127'). Please help. I'll give any information you need. My PC's specs are listed on the left, under the section called System:

Thank you for your time...

Is anyone willing to help? I am new to this
