High Pitch Squeal

I've found that many people have asked about it, but nobody has gotten an answer. During moderate to hard acceleration there is a very loud squeal coming from my engine compartment - belt was replaced recently and its still there. It seemed to be reduced for about an hour after I got my car back then returned right back to being as loud as ever.

Some people have cited the tensioner or some sort of PVC leak causing the noise, and I just want to see if anyone out there has any clue the source of this noise. Pretty disappointing because this is a great car otherwise.

Has anyone solved or identified this issue yet? Our 2008 G6 convertible squeals from 2000 to 2300 rpm and then stops. Sure I can turn the music louder or baby the acceleration but they don't fix the problem. Any help w/b appreciated.
