Set the track to be a mono track before recording. RB will intelligently put them on separate mono tracks for you, using the next available blank track. It sounds to me like you are recording to a stereo track.

You don't use the dropdown to enable inputs, you use the audio drivers section to enable inputs to be used. The dropdown you are looking at is for playback port I believe. If you have more than one playback port enabled (again in audio drivers, but on output side) you'll see more selection in that list.


Make your sound your own!
