Not stumped, just seeking similar experiences. Recently I noted a slight buzzing (mechanical, not electrical) from the engine compartment that follows RPM, in gear or not.
Tracked it down to the serp belt area. Doesn't sound like it's coming from the air pump, the alt and AC compressor are fairly new - so I'm thinking either the tensioner or the PS pump.
Opinions welcome.
