Add a mute button for gunshots upon death / while spectating

Hi everyone! I'd like to suggest a couple of small Quality of Life (QoL) improvements for the game.

When you die and switch to spectator mode, the constant sound of nearby gunshots can be extremely loud and overwhelming, leading to audio fatigue. It would be great if developers could add a quick button on the death/spectator screen to temporarily mute game audio (or drastically lower weapon sound effects) while waiting to respawn or until the match ends. I think this would be a fantastic accessibility feature for many players.

On a related note, the sound that plays when opening the game is also very loud, and there's currently no way to adjust it. Adding a volume control for this would help avoid unpleasant surprises, especially for players using headphones.

Thanks for reading!
