I started using Audacity a few months ago. I did not not have any problems at first. Now, after getting a virus and having to reinstall audacity after the virus was eliminated, whenever I try to record, it looks like I am recording within audacity, but when I listen back, I hear nothing. I am currently using a different program and it works fine in the meantime, so I know it is not my computer, microphone or headphones. It has nothing to do with my computer and sound as far as I can tell. What is going wrong?
