Hello,
I have an Intel motherboard DG45FC with a 7-STABLE from 2 days ago.
Everything is fine, except that the sound is not working, when I connect
hdac0: <Intel 82801J High Definition Audio Controller> mem
0xff950000-0xff953fff irq 22 at device 27.0 on pci0
hdac0: HDA Driver Revision: 20090329_0131
hdac0: [ITHREAD]
hdac0: HDA Codec #2: IDT 92HD73E1
hdac0: HDA Codec #3: Intel G45 HDMI
pcm0: <HDA IDT 92HD73E1 PCM #0 Analog> at cad 2 nid 1 on hdac0
pcm1: <HDA IDT 92HD73E1 PCM #1 Analog> at cad 2 nid 1 on hdac0

pcm3: <HDA Intel G45 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0

snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex default)

snd_hda [MPSAFE] (0p:0v/1r:1v channels)
pcm2: <HDA IDT 92HD73E1 PCM #2 Digital> at cad 2 nid 1 on hdac0 kld
snd_hda [MPSAFE] (1p:1v/0r:0v channels)
pcm3: <HDA Intel G45 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0 kld
snd_hda [MPSAFE] (1p:1v/0r:0v channels)
I set hw.snd.default_unit to 3, but there is no sound over HDMI.

Hrm, I wonder if the audio codec still needs to be setup. The radeonhd
driver has an Audio option to get the codec setup properly, but I'm not
sure about Intel. I don't have anything to output an HDMI stream to
right now. I'll try to poke around and see if I see anything.
