One thing I noticed the other day on one of my chain rings is that the inside of the tooth cut out profile had some burrs on it. I took a whetstone and polished off the burrs and that stopped the noises that were happening on that bike. I don't know what caused the burrs. They may have been there from manufacturing. The chain is not stretched and the chain line is fine. Anyway that might be something to look at.
