An odd problem: When I press the button on my controller to activate the analog stick, a constant pounding sound comes from the game. The game and controls are functioning normally otherwise.

When I deactivate the analog stick, the sound goes away, but I can only use the digital pad to move, which is less than ideal.

Anyone else have this problem?

I'm using a Sony PlayStation 2 controller with a RadioShack USB adapter, and the latest version of Jotun.
