From receiver through A to D converter, into IMac vis USB, but Garage Band doesn't "hear" or record the audio track. Why?
Trying to record using Garage Band from my receiver into my IMac. RCA plug into Analog to Digital Converter. USB plug from converter into IMac. I set my preferences in Apple and in Garage band to input USB Audio Codec, but Garage Band won't record or "hear" the music. What am I doing wrong?
iMac, OS X Mavericks (10.9.5), Parasound Analog to Digital Convert
