Jon: The Intel HD Audio Controller is implemented by several codecs (from Realtek, Connexant, Sigmatel...): My laptop for instance has a Realtek AL268 codec.
The current HD Intel driver fully supports some codecs, partially supports some others and doesn't support at all others.
Hence the multiple bugs. Hence the different support : For some mics works, for some speakers are automuted...

You can check your codec with this command :
cat /proc/asound/card0/codec#* | grep Codec

I think we should complete the description on the wiki (and the bugs too) with the codec name.
