I had this bug since Patch 7.
Basically, one of your saves randomly becomes "corrupted", and a lot of sounds stop working: sheathe/unsheathe, most impact sounds (you still get the whiff and some special effects, but not the basic hit sound, very noticable when hitting the ground or a dummy with ranged attack).
I have old saves from 2023 that work fine, but as soon as I load one of the bugged ones, the sounds stop working properly on all saves, and I have to restart the game to get the old ones working again.
I’ve tried verifying the game files, doing a clean reinstall, and purging the game files. I read on some old posts here that people had good results deleting .pak files from previous hotfixes, but now it’s Patch 8 and those files aren’t there anymore.
Has anyone been able to find a solution ? I really hoped that Patch 8 would fix it.
