Ipod touch cant adjust sound

Hey, as the topic title says, i cant adjust the sound. It's stuck below half way, and everytime i slide the volume control up, it just goes back to its original place. Help?

Go into your settings and adjust the maximum volume. iPods of all kinds tend to come with a maximum volume option. It sounds like yours is set to halfway.

Nah bo, it was already on full.Edit: I lowered the limit today, and the volume went up. WTF?? Model is A1213 if it helps.
