@zhead_ Sorry to hear that you have not been having a good time with the audio in-game.
Can you provide any video examples of audio problems you have listed? We can send these off to the team so they can take a closer look?
You don't even need to go that far into the game to even notice the audio issues that everyone has been commenting about.. Here's a video at the very beginning of the game the guys says "Eivor, here's a tune for you! One to liven your step." Proceeds to play and there's literally zero music coming from him playing.
