Sculk Spreading has no sound at all after beta 1.18.30.26 was released. It has sounds before, including bubbling charge, placing sculk sensor and sculk shrieker sounds (only when spreading) and sculk spreading sound (converts any natural block into sculk). It was in beta 1.18.30.22.

How To Reproduce

1. Place a sculk catalyst
2. Kill a mob near sculk catalyst
3. The sculk should spread with sounds. 

Expected Result

It spreads the sculk with bubbling charge sound, spreading sculk sounds, and placing sculk sensor and shrieker sound when spreading.

Observed Result

When spreading, there is no sound at all.
