HZD - Any way to lock the camera and turn down the volume for the 'whistle'?

The 2 most annoying features in this game. The camera and goddamn loud af whistle.

Trying to enjoy the game but the camera angle switching side to side is really bugging me. I have to keep aiming my bow to align it back to normal.

I have my volume set at a fairly moderate level but when you whistle for a mount, it's really damn loud. Especially during the night when I'm half asleep.
