   I would guess that you're hearing the blade teeth rubbing the insert as the blade rotates.  No blade runs perfectly true, so there will always be a bit of wobble as it turns.  You will also cause some small amount of deflection as the blade cuts thru a piece of stock.  (Wood density varies along the cut line, but the blade wants to follow the path of least resistance.)

   I usually get some new noises when I first use one of my home made zero clearance inserts, but they disappear after a few cuts as the blade slot becomes slightly larger.

   That's normal. Iffn it bothers you, take a thin file or wrap sandpaper around a comb or something thin, and knock the edges off ever so slightly.

   I was trying to find a way to open the opening slightly without sacrificing my zero insert support, sometimes the answer is right in front of your face, thanks Dave

   I know. I find that particular noise annoying, myself.

   There's usually a little slop in the fit of an insert into the table. Try lowering the blade and slipping a putty knife or a shim shingle into the gap between table and insert to force it to one side, then run the saw and slowly raise the blade to cut a shade more off the slot; repeat for the other side.
