So I'm considering buying an Xbox. My problem is, I have no idea how to handle the sound. I'll connect the Xbox to my BenQ 24" monitor through HDMI, but I'd rather not use the crappy speakers in the screen. My preference is to use a headset so the rest of the family doesn't have to hear people getting sawed in half while I play Gears 2. It will be setup next to my Macbook Pro...can I route the sound through that? Is there a good, low cost solution?
