OK, it's good to know.  It means that the pin-sense reports only the
pin-detection but nothing else unlike other codecs.  So, it's
basically bad to use generic HDMI parser for this codec.

And, when you wrote "I still can't run speaker-test with more than 2
channels", do you mean that you got an error?  How did you run?
With the patch, the driver should take up to 8 channels.  If not,
something was wrong -- either the patch wrongly applied or the patch
wasn't enough.
