Can you get a recording of this noise? I just want to make sure what I am thinking it sounds like, is in fact that it sounds like.
Also, I would take a can of WD 40 and use the straw to spray each pulley individually to see if it goes away. More then likely this is a pulley bearing but we need to start to narrow this down. Also, you could get the engine hot and then remove the belt and start the engine again and see if the noise is gone. Then we know for sure it is a pulley/belt issue and we just need to find which one. I would think it is the idler pulley.

Let me know if you can get the video and we can go from there but I included the process for this pulley below.
