I've noticed with TBM version 1.1 using X-Plane 11.30b2 that there is a repetitive sound in the cockpit when cold and dark that sounds like a radio static popping noise.  It's not real loud and not a big deal.  I have TBM version 1.09 installed using X-Plane 11.26 running on the same PC and there is no static noise.  I'm not sure if it's an audio bug with TBM version 1.1 or an X-Plane 11.30 issue.  I am curious if anyone else has noticed it.
