Note Blocks will play when covered by some non-solid full blocks

Thank you for your report!
However, this issue is Working as Intended.

The report you have submitted is working as intended: this is mentioned in the 22w13a changelogs — Only wool and wool carpets now block the sounds coming from noteblocks

Please note, that mechanics of the game may change between updates.
Things such as graphics, sounds, world creation, biomes, redstone, villagers, and animals may not work the same in current versions.

This change decreases the fun while playing for many people, since nearly every redstone contraption turns into a annoying noisemachine. The technical minecraft comunity would welcome it to revert to the old behaviour.

Please revert this. Noteblocks should not make a sound when something is above them. If it stays like this, all redstone contractions with noteblocks will suddenly be unpleasantly loud. This will decrease the fun for many redstoners and force them to turn off sounds.

Why was this changed in the first place? What is the benefit for a normal player? I guess it was changed because of the allays. Who would need this "feature" for their allay (which, by the way, is an extremely rare mob)? Why would they link their allay to a noteblock, which also happens to have a block above it? They can just leave air above the noteblock in that case. Why is this more important than all redstone contractions that use noteblocks and the fun of redstoners?

Go to the feedback site for feedback, this is not the place for suggestions. (Asking to revert a change is a suggestion.)

It has been reverted! Thanks! https://www.minecraft.net/en-us/article/minecraft-snapshot-22w15a
