@pandusen As Teddy said above, you can't passthrough a PCI bridge, so there's no PCI devices xapi shouldn't omit here.
I am not trying to pass through the bridge only the end points. The Intel arc's have 2 end points: The GPU and the Sound device. "xe pci-list" only reveals the GPU, not the sound device. (this works for nvidia and AMD)
But "going the xen-cmdline way" shouldn't break anything, that's what xe pci-disable-dom0-access does behind the scenes. What issues did you see? Which steps did you follow?
the sound device is available in the lspci list and can be passed through using CLI.
But doing so, (using CLI for passtrough) undoes everything done using xe or the passthrough gui in XO. and results in this:

so yes, its does break something.
