Whole project is recorded on one track

Unpublished

When I record a new track, the rest of my project is also being recorded. How do I fix this?  

Check the input settings on the sound card's software mixer to ensure that only the input you wish to record from is selected as the input device.

Make sure that you do not have the sound card's wave output (often listed as "Wave" or "Wave Audio", on some cards "What U Hear" or "Mixed Output") selected as an input device. 

This problem can also occur when you are recording from a microphone and it is picking up the output of the computer's speakers during recording.

If this is the case, turn down the speaker volume or use headphones instead.
