Put the summary of the bug you're having here
What I expected to happen was...:
Water doesn't mute noteblocks since its not a solid block
What actually happened was...:
The water block prevents note blocks from creating sound
Steps to Reproduce:
1. Place a note block
2. place a water block on top of the note block
3. try using the note block
per minecraft.net:
— A previous change to Noteblocks that only Wool and Wool Carpets would block the sounds has been reverted
