Sound only coming out of one side of headphones

I’m playing short sound clips using audio.loadStream and audio.play but when I test on my Nexus 7 audio is only coming out of one headphone.  Does anyone know what may be the reason for this?

Couple possibilities:

The sound file is stereo, and only has audio on one channel.

Your headphones might not be in all the way into the plug.

Just guessing!
