Sound works through headphone jack but not internal speaker

While listening to Pandora today my internal speaker simply stopped playing, but sound still works through the headphone jack.  It's not on mute, and I did a troubleshooting check.  When I checked the sound meter, it is moving as if it is still plugged in to a headphone jack, which it is not.  Any ideas what suddenly happened and how to fix it?
