Do the other analog inputs on the roboRio have something plugged into them?

Earlier this season my team had a similar issue where the gyro would drift steadily when the robot was stationary and would jump 10-20 degrees whenever we drove the robot quickly. At first, we set a deadband on the gyro in the code, which helped, but did not fully resolve the issue. We then printed the values of the other analog inputs on SmartDashboard and found that when we drove the robot, those values would oscillate wildly, which we assumed made noise one the gyro's signal. To stop this, we plugged in jumper wires going from the ground to the signal of each unused analog input port to keep them at a constant value, and that fixed the drift for us.
