This is an updated patch for the Apple iMac 9,1 model to add sound.
Original patch posted here:
http://article.gmane.org/gmane.linux.alsa.devel/61361/match=

I have been using this patch for a while now
and have to say it works vary well, except for a few minor 
things:

	With the iMac 24-inch 3.06GHz Intel Core 2 Duo
	everything seems to be working as it should,
        although I have not looked into the microphone
	(never really use one, nor have any apps to test,
	my guess is it doesn't work, or I never figured out how
	to get it to work).

	With the iMac 24-inch 2.66GHz Intel Core 2 Duo
	everything is the same as with the above machine 
	except I'm hearing a light scratchy/distortion noise
	come out of the speakers when using headphones(above machine
	does not do this).

Other than that the sound level is great(especially with good Dj headphones).

STAC/IDT codecs seem to behave weird when SET_PIN_SENSE verb is issued
before reading the jack-detection although the TRIG_REQ pin capability
is given by the hardware.

Since snd_hda_jack_detect() issues the SET_PIN_SENSE verb simply judging
from the pincap, we have to revert the change in the commit
  d56757ab
    ALSA: hda - Replace the rest of jack-detections with snd_hda_jack_detect()
to plain GET_PIN_SENSE verb without triggering.

The mute-LED isn't synchronized with the actual mute state on some
HP laptops with IDT 92HD83xxx codecs.  A similar hack using
check_power_status callback is added for this codec, too.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The dual-headphone mode with STAC/IDT codecs is useful only for machines
that have two (or more) built-in headphones.

But, some HP laptops give multiple headphone pin configs, one for the
built-in and another for the separate (likely a docking station) one.
This results in a missing speaker volume control.

This patch adds more check for the dual-headphone mode to avoid this
problem.

We tracked down the first-0.5s-hdmi-audio-samples-lost problem to the
AC_VERB_SET_CHANNEL_STREAMID command. It is suspected that many HDMI
sinks need some time to adapt to the new state.

The workaround is to avoid changing stream id/format whenever possible.

The ALC262 has a quirk entry matching with all Sony Vaio laptops
to use model=sony-assamd as default.  But, model=auto works much better
for new models in the recent driver versions, thus it's safer to disable
that default quirk entry.

The beep_mode option value was wrongly defined: it must be 0 = off and

Also, evaluate the beep_mode value at snd_hda_attach_beep_device()
properly so that no device is created when beep_mode=0 is given.
