I record video game vids for youtube and I've been using steromix to record because it lets me pick up my voice as well as ingame sound. Problem is i've been trying to do a co-commentary with my friend but when ever I record with steromix he gets an echo, considering it seems I'm giving out steromix as well, is there any way around this? or a way to fix it? Also on a side note. I can't use a usb headset considering it only record my mic and not ingame sound(and doesn't let me use steromix to record) is there anyway I can record more than -just- my mic with a usb headset?
