However....... I am not believing your statement as copied above. I do computer recycling for a local organization in Chico, CA, and am their sole Mac technician/volunteer. Every G4 tower that has come through our program has had a built-in microphone socket in the back panel and the default system control panel for sound output/input clearly shows the ability to use the external microphone socket for recording vocal sounds or audio files by use of a microphone or line input cable. Exactly which model Macintosh are you using for your Linux system? If I correctly recall your original posting, you are using a G4 tower?
