It's been my experience that when a device is an "Unknown device" to the 
kernel, it ain't gonna work. You might think about upgrading your 
kernel, or boot off a Knoppix CD to make sure that the sound system 
works there before upgrading.

What's the result of "lsmod"? Which modules did you load by hand? I 
suspect you'll need one like "i810_audio".
