Everytime I press "H" it mutes the audio

I never realized how much I click the letter until now. I use a Roccat keyboard, and for some reason whenever I press the letter my audio goes out. The keyboard is not new or anything, but I've started to use it again and this is happening

Is there a way to simply turn of my keyboard controlling my audio in the first place?

EDIT: Also whenever I click the mute botten is both mutes and does "H". Weird...
