I am using the latest update of Cakewalk. I'm just using the standard downloaded version with no extra plugins and just using a normal headset w/ mic. I'm attempting to do vocal recording from the headset mic on one track while listening to the other tracks. Previously, I had no troubles with this at all. It worked great. Now, I'm having troubles. The recording level drops to nearly nothing if I don't mute all of the other tracks. If I record with all other tracks muted, the recording level is fine. As soon as I try it with even 1 track unmuted, the level drops. The waveform is nearly flat. If I listen to the recording, it is inaudible unless i pump my volume all the way up and hear it very faintly. The levels look good before clicking the Record button. I can provide any information you need. Thanks!
