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?

Gib einem Hungrigen einen Fisch, und er ist fuer einen Tag satt.
Zeig ihm, wie man angelt, und er poebelt Dich an, dass er besseres
zu tun haette, als Schnuere ins Wasser haengen zu lassen.
