[alsa-devel] iMac 9,1 sound

I was able to get sound working on the new iMac by adding the following to

case 0x106b4900: /* iMac 9,1 */

underneath line 7013
case 0x106b1000: /* iMac 24 */

(this kept it from using the alc883 since the revision_id is 0x100103).

I did find though, that using the mbp3 option is what allowed sound to
work.  The same issues with the macbook pro aluminum apply here.  the
channel must be switched to 2ch to mute built-in speakers and to 6ch to
unmute.  There is another issue here though.  the playback from the speakers
is barely audible, i'm guessing it's similar to the issue with the right
speaker on the macbook pro.  I'm guessing there needs to be adjustments to
the pins defined.

If there's anything else I can do to help this along, let me know.  I do
have the macbook pro aluminum, so I can test there as well.
