I'm offering a $300 reward to anyone who will successfully provide/commit a patch to the audio library so that I can call volumeInput(); and receive the volume level from windows (and I guess any other OS that follows the USB spec). This is similar to the volume(); call that currently exists but for the input level. If you figure this out I'd bet its a total of 3 lines of code.
