>Description:
Sorry for my bad english, but:
i was fix support of integrated audio card in new chipset Nvidia nforce
61xx/MCP 410/430. 
In dmesg i see that os found my audio, them i try to load all audio drivers
with 
#kldload snd_driver
it did no find anything.
But i find, that audio codec (Realtek ALC850 AC97)is supported by os
(/sys/dev/sound/pcm/ac97.c)
i go to the google, and no found fix of this problem, but i find how to
path /sys/dev/sound/pci/ich.c for the support of nvidia 2 audio in FreeBSD
4.11.  Id of this card i found with pciconf -vl.
i add 3 lines to this file and my audio recognized with kldload snd_ich
and work as good.

My motherboard is AsRock K8NF4G-SATA2, chipset NVIDIA GeForce 6100 +
nForce 410 MCP;
 
i add:
------------------
case 0x026b10de:
device_set_desc(dev, "nVidia nForce 410 MCP");
return BUS_PROBE_DEFAULT;
-----------------------
in case structure in middle of /sys/dev/sound/pci/ich.c

PS.  I look in CVS Tree and no found fix of this.
PPS. I think that is not serious bug, but it add to FreeBSD more functionality.



>How-To-Repeat:

>Fix:
add to file /sys/dev/sound/pci/ich.c 
-------------------------
case 0x026b10de:
device_set_desc(dev, "nVidia nForce 410 MCP");
return BUS_PROBE_DEFAULT;
-----------------------
