Alesis Protrack for Line Outs

I'm trying to debug why the Alesis ProTrack for iPod and iPhone can't play through the line outputs. It's a bit hard to debug because the protrack doesn't have a USB port, so I have to log everything. When I plug the iPod touch 3rd Gen into the protrack, it seems the Property Listener is called twice in succession, first with "NewDeviceAvailable" and "Speaker" as the old and new route, and then immediately again with "CategoryChange" and "LineOut" as the old route and "Speaker" as the new route. I never get "LineOut" as the new route. The log is below. Does it have anything to do with the exceptions thrown after the microphone arrives? Happens on iPods and iPhones alike. Thanks for any input.

Hamilton
