ETS2 - Sound Fixes Pack V21.20 (1.40.x)

CHANGELOG 21.20
Added possibility of dry wiper screech or squeak sound when you use the windshield wipers on a dry windshield (for default wiper sounds).
This will work at the start of your game session before it rains. It will reset to the normal wiper sound when the windshield gets wet.

CHANGELOG 21.19
Fixed issue where wiper stick sound volume wasn’t adjustable by the interior sounds slider.
Reduced volume of rain sounds for more balance with other sounds.

CHANGELOG 21.18
Redone wiper sounds.

CHANGELOG 21.17
Finetuned wiper sounds.
