I have audacity for windows 7. I can get thru all the manual until I try to play the song that I have recorded. regardless where I locate it desk top or audacity , I don’t get a playback
If you’re using a USB device for recording, see this FAQ: http://manual.audacityteam.org/o/man/faq_playback.html#usb
If that’s not it, you will need to tell us a lot more about your setup and what you are doing (https://forum.audacityteam.org/t/how-to-post-a-question-on-the-forum/23175/1)
