Ok I need some help. I am using a 800 Mhz iBook, and I just bought an Edirol UA-1A USB Analog Audio Capture Interface. The only problem is that I am not able to adjust the input level. The level is set too low and everything I try to record is way too quiet... I am able to adjust the level for the built in audio in, but when I switch to the edirol, the option goes away. I am recording into deck 3.5 right now... it was a gift... seems fine for what I need at the moment... any ideas???
