Okay, the volume on the headphones is great. But when I turn it up ALL THE WAY on the speakers, you can still barely hear it? what is that about? Can anyone help me out with that? Also, when I record, I get a crackle noise sometimes in the vocals. I messed around with the latency thing and on both 336 and 2665 there is a crackle sometimes, not all the time. About half the time. Someone help me out with that?
