Loss of sound

I have version 2.0.5 Audacity for windows 7. I obtained the .exe installer. With the software installed I have no sound when using my music files with the Audacity software not in use. How do I correct this?

Please try explaining that in more words. I’ve now read it three times but sorry to say I still have no idea what you are trying to do or what equipment you are using, or what is happening, or what you think should be happening.

If you have previously recorded from a USB device, read this for how to reset Windows to the correct playback device: http://manual.audacityteam.org/o/man/faq_playback.html#usb.
