I'd lean towards a pulley before messing with the alternator.
I've replaced 2 so far. Stupid me, need to do the rest.
Tensioner pulley seized and ate the belt.
Lucky I'm mechanical and have another car.
Ran to dealership, got parts, replaced and back on the road.
Get a long screwdriver, like 2 feet or a metal rod, put it up to each pulley, being carefull of course not to get caught up in the belt, and then to your ear with the engine running.
And also to the alternator. You will determine with your own senses what's making the noise.
