[snipped myself]

I also would like to know (if anyone is reading this):

1. Why do I need to write another module for my device? Is it not
possible to make it work
with snd-usb-audio?
2. The device uses ac97 chip, could I use some ac97 common code
instead of rewriting it myself?

Currently, v4l drivers that must support alsa rewrites a lot of stuff.
I'm not sure this is the *right thing*.
