If you've adjusted the chain by moving the rear wheel you may have slightly put it in a different position.
So the noise "could" be the chain cutting a new path on the plastic chain guide?
Tends to sound worse when people upgrade to new heavier duty chains, it makes a buzzing/rubbing noise.

If its cutting a new path, its too tight.

Or a heavier than standard replacement chain, they need a bit of bedding in when first fitting, which is what causes the loud noise. Had it myself, and others on here have had it as well before, it's nothing new.
