I'm having trouble with passing through my motherboard's HD Audio device, and wanted to try disabling the virtual one provided by the Q35 machine as a troubleshooting step. Is there any way of doing this without switching to the I440 machine model? Alternatively, are there any negative consequences of changing the machine model? I'm using PCIe passthrough for both the HD Audio device and an nVidia RTX3050; I've seen previously that just passing devices through as regular PCI works even though the physical device is PCIe, but I'm not sure if there are any performance or stability issues caused by doing so?
