Hitting many enemies at once with Chain Lightning bypasses volume settings and can cause extremely loud game sounds

[actually-a-cat]

Describe the bug

To be clear, I mean real-life sound, coming out of the player's computer when using a soundpack, not in-game sound.

Due to the way sounds stack, when the same sound is triggered many times, its volume increases. There seem to be no limit to this, and when a sound repeats hundreds of times in a turn, the sound can be EXTREMELY loud. I'm honestly not sure how the game is managing to make my headphones emit a sound this loud, but with the system volume at 65%, and the game's sound effect volume at 10%, it was loud enough to cause me physical discomfort and I had to completely mute the game until I stopped using this ability.

Attach save file

Steps to reproduce

Install a "sounds" version of the game, enable sound and the CC-Sounds soundpack, load provided save file, shoot a chain lightning into the crowd of zombies. I suggest you turn your volume very low before you try this. As in, 1%.

set in-game sound effect-volume to a low value (e.g. 10%), note how quiet the sound effects are. Shoot a chain lightning into the crowd of zombies, compare how loud the sound effect for that is.

The sound happens when the chain lightning is done spreading.

Expected behavior

Not exploding the user's ears and/or sound device

I can confirm audio stacking using CC sounds & the save file, but not the dangerously loud part(running sound effects 100%/computer volume 70%) 🤔

Something that I didn't think about but is absolutely relevant that my setup includes a powerful headphone amplifier, which is why it's physically capable of blowing out my ears. It normally doesn't, because I turn volume way down in applications... but I guess that's a mistake, I should be turning down system volume. And indeed, if I set volumes to 20% system 100% game instead of 65% system 10% game, the balance is much better.

Nonetheless it's an issue that the noise stacking can produce max-volume sounds when sound effect volume is set to 10%.

This is a VERY SERIOUS accessiblity issue. Ear damage is not a joke!

This is true
