Great, that's what I meant with "Or am I somehow able to tweak it? Is
there a module parameter to set this SSID bit?" :)

$ for i in /sys/class/sound/hwC*D*/subsystem_id; do echo "$i: $(cat $i)"; done   
/sys/class/sound/hwC0D0/subsystem_id: 0x1043829f
/sys/class/sound/hwC0D1/subsystem_id: 0xffffffff

So, obviously the first check in
	if (ass != codec->bus->pci->subsystem_device && (ass & 1))
is false. How can I tweak the subsystem_id least-invasive not to match
codec->bus->pci->subsystem_device (which should be 0x829f then) anymore?
