Hi Gale,
Thanks for hanging in there with me. I'm thinking maybe Audacity isn't compatiable for laptops due to built-in speakers and microphone.  Have you heard anything to that effect?  I do have a microphone outlet if I want to use an external microphone. My husband is a songwriter, and we are trying to record and burn a CD for guitar demo...one track, no effects. He has a friend who has used Audacity for simple guitar demo, but he has PC not a laptop. Prior to trying to adjust Audacity, I could play songs we copied to files from my husband's CD. Now the existing songs in our files won't play either. I must have turned something off or on trying to get Audacity to work. Anyway, thanks for the help you have given to us.
Have a great day,
Diane
