Hello all. I'm new to the forum and need a little advice. I recently bought Pro Tools Express with an Mbox 3 after using PT SE with the Fast Track interface for a couple of years. I am having a lot of difficulty with trying to get sound through my mic. The first time I hooked it up for a test run it seemed to work just fine. But now, for some reason, it won't work. The only time I can hear anything is when I shout into the mic, and that's barely audible. I've checked the cord, and unplugged it a couple times so it appears the connections are all good. Any ideas as to what might be causing this problem?
