GarageBand/iPad2 - No sound
This may sound very simple, but here's my problem:
I plug my guitar in to my iPad2 to use the guitar amplifier in Garage Band. No sound comes out of the iPad when I play. I can see the green light above the cable icon in GarageBand, so I know it's getting a signal from my guitar. I have tried switching on "monitor", but to no avail. It looks like a great app, but it can't seem to do one of the most basic things it's supposed to do.
What am I doing wrong?
iPad 2, iOS 4.3.3
