Audacity Forum

Sorry for my english ;(, the problem is that all the tracks just went transformed into a horizontal line, so when I play the tracks nothing sounds, and the "mute" option its not even activated. It just went from normal tracks with sound to that horizontal line with no sound.

I wanted to record a voice on a new track and all the other tracks stayed like that, now nothing can be heard. I have been looking for ways to fix it but nothing has come of it. Help please, it's an emergency
