If you’re recording throuhg the line imput of your sound card, then you have to go into the Windows sound section and set to record and mute all but the line-in.
Double click the speaker icon in the system tray, select options-properties then check the record box. Then you can adjust your recording preferences.
After that follow Gary’s instructions. Add an audio track and arm it.
This is what I had to do to make my vo’s. You’re not seeing the waves because you may not be actually recording.
