CM2250 loud engine whine, need advice

My truck is a 2013 Peterbilt 386 with a CM2250. The truck has an engine whine that is considerably louder than the motor running. You can hear it from across the parking lot. It sounds like a PTO running or a supercharger. It gets louder with rpm as well. I spoke with rawze and he mentioned it could be the oil pump TSB.

Does anyone have any suggestions or insight on what could be causing this?

Here are links to 3 different videos I recorded so you can hear the noise.
