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 
the computer to the LCD-TV via HDMI. From dmesg I got the following:

hdac0: <Intel 82801J High Definition Audio Controller> mem 
0xff950000-0xff953fff irq 22 at device 27.0 on pci0
hdac0: HDA Driver Revision: 20090329_0131

pcm2: <HDA IDT 92HD73E1 PCM #2 Digital> at cad 2 nid 1 on hdac0
pcm3: <HDA Intel G45 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0

/dev/sndstat is saying:

snd_hda [MPSAFE] (1p:1v/0r:0v channels)


I set hw.snd.default_unit to 3, but there is no sound over HDMI.

TIA,

Harald
