I have been flying today with this update and the Windsound was extremely annoying. I was looking everywhere in my cockpit for thing I could have done wrong or doors I might have left opened and then I found out that it’s tied to the speed of the Wind and the direction.
So if you can’t hear it, make sure all your sounds in the MSFS sound Settings are on 100. Then while flying play around with the weather. Set a wind-layer to your altitude, max the KT of the Wind and make sure the Wind is pointing directly at your nose. And I‘m pretty sure you will get what we mean.
