Audacity Forum

In Devices there is no other choice apart from Built in Output and built in Microphone. Do I have to plug in the iMic before it is detected? Sorry I'm a total newby at this!

I downloaded the new audacity program, my operating system is Mac OS 10.7.4. I'm using a little walkman cassette player,a griffin iMic and the relevant connection. When I play a tape the sound doesn't come through the computer speakers (the sound is on ); all I hear is high pitched squealing noises....
