Thomas,
To tell you the truth, I thought I already had the ability to choose from sound devices, since there is a drop down menu called "Record from this sound device". So, I would vote for making this a real choice, since that is what the interface leads me to believe.
In many cases (like mine, knowing that the Logitech webcam device is not correct) the choice of sound devices will be obvious, in other cases, a little trial and error should work.
Thanks as always,
Mark
