Could be alternator whine. My car sounds supercharged as well. 4.8is 2006.

whine on acceleration? or constant?

Quieter at idle. Sounds like I am supercharged under acceleration.

I was thinking it could be some pulley as well, but it is really not on my list of priorities to address yet, so it will have to wait.

That is the generator whine.

That is actually what I figured. Any remedies to the problem, or only to replace it?

I tried once to get one rebuilt but they could not do it. Just replace the damn thing
