How can I tweak the subsystem_id least-invasive not to match > codec->bus->pci->subsystem_device (which should be 0x829f then) anymore? Usually the codec SSID isn't checked in other places, so passing a bogus value should be OK. Pass a value like 2: # echo -n 2 > /sys/class/sound/hwC0D0/subsystem_id then # echo -n 1 > /sys/class/sound/hwC0D0/reconfig The latter needs that the all sound device files are closed beforehand.
