I've got the above coming in the Post and I was wondering how people have set this up correctly?

I would like, in an ideal world, to use my current soundcard as my media output and for phone and voice commands use the USB-SA (as it's designed to be used).

So when I have a call, my media is muted and the USB-SA is used as the output going through the line-in on the main soundcard... if that makes sense?

Thanks in advance!
