Summary:                    Alsa 1.0.10 & 1.0.11rc2: STAC_9223
unsupported/errors, only oss-emulation works with 2 channels
Description: 
As in summary, alsa 1.0.11rc2 works not at all, alsa-kernel 1.0.10 only
with oss-emulation and 2 channel stereo.

My Board is an 
Intel Desktop Board D945PVS with 7.1 Surround Sound (Sigmatel 9223)with 5
analog jacks in the back, 2 on the board (Front Panel) and a digital jack
in the back.

The mixer shows only a "Front" (somtimes a "Headphones" on 1.0.11rc2)
device.

When starting "aplay" i get:
  ALSA lib pcm_direct.c:783:(snd_pcm_direct_initialize_slave)
snd_pcm_hw_params_any failed
  ALSA lib pcm_dmix.c:831:(snd_pcm_dmix_open) unable to initialize slave
  aplay: main:544: audio open error: Invalid argument

also on every other alsa using software

I'v taken a look into the "[cvs/1.0.11rc2] patch_sigmatel.c" and there
probably should be something like (After Line 277):
        { .pci_subvendor = PCI_VENDOR_ID_INTEL,
          .pci_subdevice = 0x0707,
          .config = STAC_D945GTP5 },    /* Intel D945PVS - 5 Stack */

but for me this changed nothing... 

The output of lspci is appended.

I hope this is enough information, if not tell me what you need.

PS: For me this is a major bug, butunsupported cards are generally
features?
