I am trying to get HDMI audio from a ECS 780G mainboard with sb700 and built-in graphics Chipset: "ATI Radeon HD 3200 Graphics" (ChipID = 0x9610). The HDMI video is working with the xf86-video-ati driver.

and from hwinfo:

running alsamixer -c1 i can unmute the IEC958, but i get no HDMI audio. Note the "...Digital Out at Int HDMI" _not_ SPDIF Out at Int HDMI.

In order to get the 'card1 with IEC958' to show up i had to add my pci-id to alsa-driver-hg20080323/sound/pci/hda/hda_intel.c

/* ATI HDMI */ { PCI_DEVICE(0x1002, 0x4383), .driver_data = AZX_DRIVER_ATIHDMI },

The original hda_intel.c has

{ 0x1002, 0x4383, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AZX_DRIVER_ATI },

Any help getting this working appreciated. Thanks.
