I flew 210 kts, sound was good. Then icing started and froze my pitot. The airspeed needle stuck at 210. I landed, parked. Airspeed needle was still frozen, at 210. And guess what....the airflow sound continued. I suppose the add-on reads IAS airspeed through simconnect (which indicates 210) while the airspeed actually is zero.

When flying the Geebee R3, in the airframe wind effect, the volume slider does not change the sound. Only sliding it fully to the left, the sound stops. But otherwise does not change.
