Cannot hear recorded tape

v. 2.0.5 / Windows 8.1

I cannot hear the tape I’ve recorded. I can hear it while I’m transferring from the cassette but after I’ve saved it as an MP3 file and then try to play there is no sound. Any advice is welcome.

If you are using a USB cassette player, please see this Frequently Asked Question: http://manual.audacityteam.org/o/man/faq_playback.html#usb
