I’ve been using audacity for some time. My operating system is Windows 7, and I’m using Audacity 2.0.4. But today, for some reason, I can’t get any sound. I’m working on a song I recorded last week. Today when I opened it in Audacity and tried to play it, there was no sound. I tried fiddling with different controls, such as the outgoing speaker control, but couldn’t get any sound. The sound on my computer is working, because I played some CDs and the sound on the computer is working fine. It’s just not working on Audacity. Anybody know what is happening? Thanks.
