Sound not coming through Earbuds

[Tom Stasio]

For the first time since having this phone, I've plugged in earbuds so I could hear the sound to a video without disturbing those around me... however the sound still came out of the phone and not out of the earbuds. Why would that happen??

I know it seems stupid, but are you sure you plugged it in all the way? Did you try testing other headphones? Did this only happen once or is it continuing to happen? It's probably just a glitch that won't happen again.
