Hi all, I am having trouble with the line-in (recording) on my tibook. At least I think its trouble, its not working. I bought a head set and microphone Plantronics audio.60, the headphones work fine and my built in microphone works fine. I plugged in the microphone line to the line port on my tibook and set the line in option in the system preference. I couldn't get any response using any software. iTunes or system pref audio...nothing. So I am figuring that the line in port is not working. Any ideas on this? Is there anyway I can check without having to send my tibook to an apple authorized dealer? I still have warranty coverage till Jan 2004. I checked the Plantronics site and it shows the Audio.60 as working with the mac system, however, maybe there are specific microphones that need to be used? Any suggestions are welcome. thanks tim tim.molnar Digital Tao http://www.digitaltao.ca 306.585.3666 tam at em.ca
