As the title states, I am trying to build my own audio device driver. Problem is, I have no fraking clue as to what I am doing!

I've put 10.4.11 on my Thinkpad X31 with very wonderful results. I have almost a perfect replica of my old 12" PowerBook save for the Intel 2100 wireless. But I digress...

I use an Echo Indigo DJ cardbus audio card for various DJ applications. Of course, runs perfect on my Windows mahcine but need some help getting a driver built for the OS X side of things. I have a folder of Echo generic source code downloaded from their site as well as XCode 2.4.1.

I tried to install the old PPC version of the driver which (obviously) didn't work, but put a kext on the machine. Not sure if I need to examine the content of that to find some clues as to how to construct a driver.

Basically, I need a lot of help. Since I have no clue about the fundamentals of Xcode I am very, VERY green. I want to think that this driver can be built, I just don't know where to start.

Anybody want to take a crack at it or at least steer me towards someone who can give me some tutorials?

Thanks community!
