   Does this patch help?

It makes the extra mixerctl knobs go away, but still no sound comes
out after suspend/resume and then detach/reattach.

When I first loaded hdaudio.kmod and hdafg.kmod, it printed the
following console messages:

hdaudio0 at pci0 dev 27 function 0: HD Audio Controller
hdaudio0: interrupting at ioapic0 pin 22
hdafg at hdaudio0 not configured
hdafg0 at hdaudio0: Sigmatel STAC9221 A1
hdafg0: ADC00 2ch: Mic In [Built-In]
hdafg0: DAC01 6ch: Speaker [Jack] [Built-In], SPDIF Out [Jack]

audio0 at hdafg0: full duplex, playback, capture, independent

When I reloaded hdaudio.kmod and hdafg.kmod after suspending and
resuming, it printed the following console messages:

hdaudio0 at pci0 dev 27 function 0: HD Audio Controller
hdaudio0: interrupting at ioapic0 pin 22

I don't think I've ever seen the `duplicate pin in association / pin
0F has wrong direction for 01' messages before.
