Grass block breaking/walking sounds are nearly silent

Several sounds regarding grass blocks are almost completely silent. Both the breaking process and walking sounds are affected by this, while placement and completed breaking/breaking in creative mode are totally fine (matching that of dirt). All of my audio settings are at 100% save for music.

Other blocks seem to function normally; stone, dirt, and sand all sound normal.

This can be reproduced by loading a world in survival mode, finding a grass block, walking over it, and breaking it with your fist.
