>Description:
The azalia device driver doesn't support pin sensing. This has to the effect that the speakers are not muted when using headphones on systems that employ Sigmatel 9220 codecs.

>How-To-Repeat:
Use headphones on systems with Sigmatel 9220 codec and notice that the speaker amplifier isn't muted to the annoyance of by-standers.
>Fix:
I failed to source the Sigmatel 9220 codec datasheet. Perhaps someone else has access to this document. Implementation should reasonably trivial.
