New Mac Pro Dual Quad-Core. Can't use Audio Input from ANY source. All three devices show up on Sys Pref Audio, Built-in, Line-in & Digital-in. With nothing connected, Built-in shows no audio level signal. Same for Line-in with a earphone/mic 2-plug wire. Audio out works fine. I have an external Bose System w/Sub-woofer, jacks for earphones & Mic, but only one wire to connect to tower Audio-Out. Output for earphone or Bose jack earphone or speakers work fine.
Still under warranty so I can take it in, but if anyone has a suggestion I'd like to hear it.
Thanks...
