Hey! There is a bounty out to make a Microphone work under Linux:

(its from a tweet @Adam Curry):

I am never posting about my audio setup or problems again. The uninformed and often snarky comments agitate me too much.

I will personally reward a $5000 bounty in Bitcoin to anyone who can make my MOTU Ultralite mk4 work with *any* Linux distro as it does under windows.

(end tweet)

Maybe it is something you know about?

Have a good one!
