The sound in the newest snapshots sounds slightly different than in 1.12.2. They sound slightly muffled, and it can be a bit irritating. If you have the same problem, please comment and vote this issue.

Same here. the audio in the snapshot makes my ears bleed. And this was my first time ever using snapshot version! No thank you anymore!
Resolved forward to MC-121364.
Can confirm; here are video comparisons of the grass breaking sound in 1.12.2 and in the snapshots. In the latter video there is a strange filtering being applied that changes the sound depending on the way your head is facing.
There was another bug report related to sound changes in the snapshots (MC-121364, resolved as intended), but I believe that to be a different issue as that report is more about sounds being too directional than being muffled.
Also confirmed for 18w07a
