Just to clarify, this particular Digital control behavior is the same on live 
Ubuntu (which uses modules and supposedly works correctly).

Also, I've posted a patch for review. It adds the quirk for my PCI subdevice id 
which is not present in the current set of SND_PCI_QUIRK. The former micmute 
quirk was picked up by the codec SSID and not PCI id. The patch fixes the 
speakers problem for me (including the built-in drivers usecase).
