Right, I posted about this a while back and was hauled up for not providing enough technical information, so I shall try to be as throrough as possible - but apologies if I miss anything out, I'm rather out of my depth here.

I am using Audition 1.5 on a PC with Windows XP. The sound card is a C-Media AC97 Audio Device, and all the setting in Windows APPEAR to be okay for that.

All seems to be working fine in Audition with sound material that is downloaded or taken directly from digital sources.

HOWEVER, I am trying to record onto it from a Minidisc/microphone, connected to the sound card with an ordinary phone jack. The sound coming from my speakers (which are plugged into the same sound card) when I play from these sources is fine - but when I record it onto Audition, it records in a distorted way with fluctuations in volume in the resulting soundwave.

My own personal deduction, which may be flawed, is that the problem is with Audition because it is the recording-on-audition stage at which things are going wrong. But I've checked everything suggested by the troubleshooting guide and have drawn a blank.

Any ideas? Please?
