I have a 2 GHz PowerPC G5 running OS X 10.5.8. I want to record my electric guitar with Garage Band '08. When I go to System Preferences and go to the Sound preferences to select the audio input, only "Internal microphone" is available as an option. There's an audio input jack on the back of the computer, so why is "Line in" not available for me to select?
Everything I'm looking up online says that all I need to do is select "Line in" in the Sound preferences, but it isn't available to me. How do I add "Line in" as an option?
