Help Volume button has a mind of its own

[thugacation]

My volume button has gone crazy, volume is going up and down at random. I think the button could be broken, but the thing is it started happening suddenly.
Is there a way to disable it and just control the volume through audiomanager?

All the apps I can find on the market that might work look like they require root. Are you rooted?
