ANother new thing I noticed: after installing (and fixing) HDAAnalyzer, as shown here, I was able to confirm that asserting GPIO 0 on the adi1984 chip sets the hardware mute feature. http://article.gmane.org/gmane.linux.alsa.devel/59132
Relevant lines from Windows .inf file:

HKR,GlobalSettings,GPIO_2, 0x00010001, 0x0000000A ; Enable HW Mute control
