You need to passthrough all the components of the gpu, you didn't pass the audio portion:

0b:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Oland XT [Radeon HD 8670 / R5 340X OEM / R7 250/350/350X OEM] [1002:6610] (rev 83)
	Subsystem: Dell Radeon R5 340X OEM [1028:0083]
	Kernel modules: radeon, amdgpu
0b:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Oland/Hainan/Cape Verde/Pitcairn HDMI Audio [Radeon HD 7000 Series] [1002:aab0]
	Subsystem: Dell Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series] [1028:aab0]

So:

    <hostdev mode='subsystem' type='pci' managed='yes' xvga='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x0b' slot='0x00' function='0x0'/>
      </source>
      <rom file='/mnt/user/Downloads/192110.rom'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes' xvga='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x0b' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x1'/>
    </hostdev>

Make sure 192110.rom is a proper vbios for your gpu.

 

You need to isolate the gpu, bind to vfio at boot iommu group 27.

not needed to see if it works or not, you can optimize eventually later.
