This cheap(est) USB sound card works pretty well on macOS *without* requiring
USB-controller-passthrough.
Since Catalina, Apple included a native virtio-sound driver, supported since
QEMU 8.2. It can be enabled by adding `-device virtio-sound,audiodev=snd0
-audiodev pa,id=snd0` to the command line. libvirt support is scheduled to be
added in 10.4.0, and could then be enabled like this:
```
<sound model="virtio" streams="2">
<audio id="1"/>
<address type="pci" domain="0x0000" bus="0x00" slot="0x1b" function="0x0"/>
</sound>
<audio id="1" type="pulseaudio" serverName="/run/user/1000/pulse/native">
<input mixingEngine="no"/>
<output mixingEngine="no"/>
</audio>
```
