I'm trying to record my music through a mixer hooked up onto my computer, the mixer is responding to the guitar but garageband isnt, I made sure that the audio driver was changed to the usb port, can anybody help
go to system preferences > sound and change the input device to your mixer if you haven't already. then go to preferences in garageband and change it in there if you haven't. other than that i don't know though. sorry.
