Totally Haywire ... &%#@!*&^

Drive class ... ???  I'm not even sure what that is which is probably part of the problem.  I can perhaps give you a few more details Steve and maybe you can connect the dots.  Typically I record with my mic, music, and sound effect levels all equal.  When I want to quiet the music and/or effects, I simply move the slider down on the Rodecaster.  That's how I control volume.  But righ tnow, I have to damn near turn them all the way down to dead silent to record at a decent level.  Even when I press record on Audition, it sounds hot and the level is moving anywhere between -50 and -30dbs ... with no audible sound in the room.  It sounds like there's energy going into Audition (too much of it).  I also tried messing around with a multitrack to see if that made any difference at all.  It didn't.  I did notice however when I clicked on the "R" to record my mic track and the "I" to hear the mic track, it multipled the sound like an increasingly loud cascade.  I don't know what happened and I don't know enough about it to pinpoint what might be wrong.  The only think I can do is provide as many details as possible and hopefully something and somebody can help.  

Any insight would be brilliant!
