I'm less concerned with the capture part of this card as I record audio
through the mic of the webcam anyway. But having added that, it hasn't
solved my previous problem with not being able to hear sounds from multiple
sources, and also I can't use alsamixer now.

So I guess that means there aren't really any solutions to my bug? What
happens next? (sorry for all the annoying questions)
