GarageBand seems to think I have something called an "iTea Aggregate" attached to my computer. Currently there is nothing connected. If I tell GarageBand to use the phantom device it tells me: "Error Code -2 was returned by the Core Audio Driver. I have looked it Audio and MIDI Setup and found nothing. Same deal in the Sound Preference Pane. GarageBand seems to think it is an output device. Does anyone know what this is? I am using an iMac Core 2 Duo running OS 10.4.8 and GarageBand 3.0.4.
