Hi Guys, I have been trying to find an answer to this all over the internet and I have found nothing.. So I have come here to you guys hoping someone might have a solution. So this is my first post and i'm far from an audiophile.. really, I know nothing. What I do know is I wish to be able to have 2 or more physical volume controls (knobs eg Keyboard scroll and additional controller like this)that control the volume of designated sources playing through the same or multiple devices. So for example. I wish to be able to play a game with audio going through a headset and listen to music through speakers and have one "knob" controlling the volume of the game and the other controlling the music playing through Winamp or what ever. Is this possible?
