Hello there Kline14,
I would recommend a couple of things. First if you havent already, turn off the iPod with everything disconnected, and turn it back on, then re connect everything. If that doesnt work then I recommend resetting the iPod.
This article outlines how to do both of those things, iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting found here http://support.apple.com/kb/ht1430.
Restarting your device
- Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
- Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If the issue still persists check out the troubleshooting section of this article: iOS: About Apple Digital AV Adapters found here: http://support.apple.com/kb/HT4108.
If the issue persists after that, then I would recommend restoring the iPod using iTunes, iTunes: Restoring iOS software http://support.apple.com/kb/ht1414. Be sure to backup the iPod first.
All the very best,
