VERY weird bug! For the last months I've had trouble with the windows sound always resetting to 20 when I played the game. I have to lower it to 10 whenever I log into the game & I didn't know why for the longest time.
But it turns out that changing the INGAME sound volume controls the windows volume when you first start the game.
I tested this by changing my sound ingame to 61/100, & when I restarted the game, windows now has 61% volume on Nin online.
I don't know if anyone else is having this issue or just my client is bugged or something?
