Exporting Audio Files

I am on Windows 7. Updated to the latest version and added the lame plug ins. I am recording audio off a record player for my grandfather. I do have clips saved in Audacity from the record player. Exported files into mp3 and wmv. When I play it in Windows Media Player I get dead air. What am I do wrong???

If it’s a USB turntable, just unplug it from the computer. See http://manual.audacityteam.org/help/manual/man/faq_playback.html#usb .


Thank You. That helped. I appreciate it. I know my grandfather will love it!!!
