I will say the idea of an audio slider for specifically creature sounds wouldn't be the worst option. Part of the reason wolves are as quiet as they are is already related to that issue, since they are also tamable and used to just constantly serenade you the song of their people at the top of their lungs. That and I honestly wouldnt mind running around the biomes I'm already used to figuring out how many weird sounds were ambiance and what was actually a critter i dismissed (I've gotten neck sounds in the swamp to and thought it was ambiance for a while, then I discovered that no, there's apparently a single large rock on the very edge of the coastline that counts as black forest in this swamp and i was genuinely hearing necks at that rock from a crypt half a swamp away...discovered thanks to an abomination that spawned at this crypt and suddenly made it much quieter when it wandered over to the rock and decimated said necks).
