Spectre Audio - Please, it's been years...

Can you please patch it so that spectres do not make any noise or at least allow the player to control the volume level independently from other sound effects? It's really hard to enjoy the environmental sounds, other effects, voices, and music, when the constant grunting of the chieftain or rain sound effects from the frost bearers is playing.

It's non-stop audio from them... I'm actually really surprised that you devs have not been annoyed by it enough to patch it by now. The number one complaint of spectres is the audio; please address this.
