I'm starting to experiment recording with my laptop. My first big trouble is that when monitoring or recording, wether using laptop mic input or USB audio adapter input, I get a HUMM noise, but only when laptop's AC adapter is plugged in. When im running just with batteries, i get no noise.
I read about ground loop issues, but since the only thing plugged to an AC outlet is the laptop adapter, it might be another thing... any help?? Thanks in advance!
