Hi Jan, I found in some update that:
Change-log 2024-05-10
- Added glider variometer sounds are now adjusted by the optional assistance "auto-cockpit". On the ground the assistance mutes the vario sound automatically and turns the volume back up after the winch launch or when the aircraft is in the air long enough during aerotow.
I used both auto-cockpit on and off options, and in none of the states the Variometer ON OFF key settings can be adjusted, nor with a joystick axis. Could you kindly check it?
Variometer sound is too loud compared with the air sound, so I need to decrease the PC volume when it is activated. Thank you!
