I am fairly new to Vegas. I am working on an Audio project and had Vegas on my laptop. I never messed with any of the soundcard parameters and I had no problem recording multiple tracks. Since my laptop died I loaded it onto my pc. It has a SB Live series audio card. When I go to lay a new track down I get all the other tracks recorded on the same track I'm recording. For some reason Vegas is recording the playback. How do I keep this from happening?
