I was working on my guardian farm when I suddenly got zapped by the guardians. I didn't realize it at first because my player sounds weren't working despite them being at 76%. I used my Riptide trident, but that didn't make a sound either because it is under players as well. This is the second time that a particular sound source has randomly stopped lately, but I have not yet figured out the cause. This problem can be solved by adjusting the corresponding slider slightly.
