2007 Buick LaCrosse Question: low whining noise at low speed, much like a noise of low power steering fluid

This noise started about three weeks ago. Since then I have replaced the serpentine belt. The noise got louder and increases with acceleration up to forty miles per hour.As far as I can tell the belt tensioner seems to be OK. The noise is constant.

    Try listening under the hood with the engine running. Don't get near any moving parts but try to locate the sound. I suspect a failing power steering pump.
    Here's a directory link for you:
