I haven't made any progress yet myself except to come to the conclusion that I need to compile a new audio driver that includes USB audio functionality.

I suspect this isn't hard, but I haven't had time to set up the environment and figure out what I am doing:-}

If someone else does, I'd love a clue as to how to best get started. It is a busy time right now, so I hope to start after finishing the taxes (.. and the mother's taxes, and the mother-in-laws taxes, and ...).

I'm an engineer, not a tax man, Jim.
