Ive read through the forums, and I've tried a bunch of stuff, but I can't figure this out and I would think its easy...maybe? I have a USB microphone. I have a TV connected to my laptop via HDMI. I have headphones plugged into my headphone jack. All this is on my new 15" MBP. I want the system audio and my voice via the microphone to go over HDMI to my TV. I want my headphones to just play the system audio and not my voice. Thats it. An ultimate 3rd thing would be able to balance the audio, but beggers can't be choosers. IS there a way to do that? Is there a 2 in 2 out mixer that I can download/buy?
