Hi Rob,

I guess the noise cancellation could be done at driver level in windows?

It's something like measuring a baseline (with the noise) then measuring 
while you speak, and substract these signals from eachother to gain a 
clearer speech. I would do that in the driver :)

So that would be alsa that needs an update, I guess...
