I have an inspiron n4110 that i am trying to use for recording usind acid pro.  the problem is when i try to record there is a small delay in the sound. This delay happens if i plug directly into the mic input, or usb using a midi controller.  I've tried turning of all the HD functions and have played with every setting i can think of. The problem is there with no software running and adjusting the latency doesn't help. My old computer with xp worked fine.  any thoughts???
