I am trying to record from a usb turntable to something that can play on my computer. It plays fine in Audacity, but when I export to a wav or mp3 file, there is no sound whatever in Windows Media Player. I am using Windows 7. What am I doing wrong?
OK, I admit this isn’t a normal problem. Export what you consider a normal, short MP3 and post it here.

Ya i need help with that one as well! The manual says to export in order to play files elsewhere but i had no success. 
Have you both tried this Frequently Asked Question:
