There are obviously designs out there like this, should the > ERR message be simmered down? Although HD-audio is a bus that can be dynamically enabled / disabled codecs, it's been supposed to be rather static and exposed only if there is really a need for it -- that is, only if there is a codec on it. So "no codec" is seen as an error for now if you try to initialize the HD-audio controller. We may downgrade it, but the situation is still not ideal either; the driver is still bound without serving anything useful, and it needs to react for the PM and other things. Since the probe of codecs happens after the driver probe stage, the driver can't go away by itself, unfortunately. thanks, Takashi
