irst time caller here with a few questions on my new MBP: I have a line in (worldspace sat radio) that is clearly working, see attached screencap, as i can record it in garage band, but the internal speakers or headphone jacks are not outputting the sound. I also have an airport express working with itunes, and once the above is fixed, i want to somehow stream the input (sat radio) to the airport express output terminal. but how? re point 1 above. in windows with soundblasters, u would set the sound card to "play what u can hear" and all would be well. On another note, i was also shocked there is no system recorder that i can find that outputs wav files. also useful. But all and all just loving this box!
