Yep, dampness makes for a louder " cracking " sound , ( not sure why ) wetting with water will lubricate the belt temporarily making the noise go away. Don't be afraid to get the belt wet, it will dry off.

Observation is just fine.

This lets us know that the compressor is OK, but the clutch is still suspect. However, given more noise then damp I'm voting for glazed flat pulleys / belt. What ever you do, _DO NOT_ use belt dressing, this sticky stuff makes a real mess, won't last and, then the noise returns it will be far worse!

This flat belt noise is common across all cars that use flat belts and can even occur with very hard old style V belts.
