Belt is fine, my first and good guess would be the bearing that is removable on the very front of the AC compressor pulley. But I understand that this bearing moves regardless and if the noise only starts when the compressor is engaged it's the bearing deep inside the compressor. The "non-replaceable" bearing.

So this is my question, would this noise (when engaged) be a symptom of the front "replaceable" bearing or we simply need a new compressor.
