What kind of mic are you using?

You're description of what gets recorded sounds suspiciously like what happens if someone uses a Phantom Powered Mic without the Phantom Power on the preamp available.

Or it could be something else entirely, hard to tell from here.

Another cause of distortion, but typically not of lowered recorded volume at the same time, is having your sound device set for anything other than 16/44.1, it is best to leave your sound device "unlocked" such that the host program, in this case, BiaB, can set its sample rate and bit depth automatically when the program opens.
