Essentially, the headphone switch is correctly muting the jack (0x80, left and right channel). Just no volume. Back to the manual. I'll try to get another patch out today.

Attached.  Quick diff for your instant gratification:

hansen:~% diff without-headphones.codec with-headphones.codec

Back to the manual. I'll try to get another patch out today.
