Yes, that's my problem indeed. I didn't mention that the module snd_hda_codec_nvhdmi
isn't even loaded at boottime. But on manual module load the device isn't avaible either.
So could it be that my device pci ids aren't hardcoded in the module source yet?
The .asoundrc isn't helping me, since the alsa device isn't created:


# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.20.

My graphics-adapter (NVIDIA Quadro FX 770M, a mobile graphic-unit) isn't listed
in alsa-kernel/pci/hda/patch_nvhdmi.c:

/*
  * patch entries
  */
static struct hda_codec_preset snd_hda_preset_nvhdmi[] = {
         { .id = 0x10de0002, .name = "MCP78 HDMI", .patch = patch_nvhdmi },
         { .id = 0x10de0006, .name = "MCP78 HDMI", .patch = patch_nvhdmi },
         { .id = 0x10de0007, .name = "MCP7A HDMI", .patch = patch_nvhdmi },
         { .id = 0x10de0067, .name = "MCP67 HDMI", .patch = patch_nvhdmi },
         { .id = 0x10de8001, .name = "MCP73 HDMI", .patch = patch_nvhdmi },
         {} /* terminator */
};

Could this simply be patched with my id?
