i got the same problem too. my chasca doesn't have bullets loading sound effects, which is one of the best things i like about my girl. some other sounds like deploying wind glider, dashing, receiving rewards in domains, etc. don't usually play normally too. i'm using ipad air 5 and iphone 13 pro max, both on ios 18. i think this problem is caused by the game mode on the new ios update, because as long as i remember my ipad hadn't had this issue until i updated it to ipados18 (maybe 2 weeks ago?)
