I am lost!! I don't know whether I have an Audacity problem, a driver problem, a vista problem, a 64 bit computer problem.!! All of a sudden the sound disappeared from my computer. I thought maybe the sound drivers needed to be updated. I did this, then I downloaded driver robot to be sure that it was done correctly. I have played around with the preferences tab on audacity. I downloaded another audacity and then all the effects dissappeared in addition to no sound, although it was the same version. The sound came back but was very tinny. I had read that beta version was unstable, so downloaded an older version. Have bad sound, but can't seem to fix it. Where are the effects? They were automatically with Audacity before. I tried to download plug ins, and did, but where are they. It's been 3 weeks, and I am at a loss.
