snd_hda on Optiplex 980

[Jonathan Chen]

Hi,

I recently migrated my 8-STABLE/amd64 system to a Dell Optiplex 980 and 
have discovered that the sound system isn't recognised by snd_hda.

cat /dev/sndstat:
   FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
   Installed devices:
   pcm0: <HDA NVidia (Unknown) PCM #0 DisplayPort> (play)
   pcm1: <HDA NVidia (Unknown) PCM #0 DisplayPort> (play)
   pcm2: <HDA NVidia (Unknown) PCM #0 DisplayPort> (play)
   pcm3: <HDA NVidia (Unknown) PCM #0 DisplayPort> (play)
   pcm4: <HDA Realtek ALC269 PCM #0 Analog> (play/rec) default
   pcm5: <HDA Realtek ALC269 PCM #1 Analog> (play/rec)

The relevant bits from dmesg appears to be:
   hdac0: <NVidia (Unknown) High Definition Audio Controller> mem 
0xf7dfc000-0xf7dfffff irq 17 at device 0.1 on pci1
   hdac0: HDA Driver Revision: 20100226_0142
   hdac0: [ITHREAD]
   hdac0: HDA Codec #0: NVidia (Unknown)
   hdac0: HDA Codec #1: NVidia (Unknown)
   hdac0: HDA Codec #2: NVidia (Unknown)
   hdac0: HDA Codec #3: NVidia (Unknown)
   pcm0: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 0 nid 1 on hdac0
   pcm1: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 1 nid 1 on hdac0
   pcm2: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 2 nid 1 on hdac0
   pcm3: <HDA NVidia (Unknown) PCM #0 DisplayPort> at cad 3 nid 1 on hdac0

And a lookup via pciconf -lvc:
   hdac0 at pci0:1:0:1:       class=0x040300 card=0x0cfb1028 chip=0x0be410de 
rev=0xa1 hdr=0x00
       vendor     = 'NVIDIA Corporation'
       class      = multimedia
       subclass   = HDA
       cap 01[60] = powerspec 3  supports D0 D3  current D0
       cap 05[68] = MSI supports 1 message, 64 bit enabled with 1 message
       cap 10[78] = PCI-Express 2 endpoint max data 128(128) link x16(x16)

Is there any chance that someone has got this working? Or that a quick 
patch of the lookup tables in sys/dev/sound/pci/hda will magically enable this?

Cheers.
