I tried to adjust the sound volume of note blocks by dragging the "Jukebox/Noteblocks" slider, but it did not adjust the volume. Instead I tried dragging the "Blocks" slider and it adjusted the sound volume of note blocks.

Note Block sound source is "Blocks" instead of "Jukebox/Noteblocks"

Additionally, when a Note packet is recieved by a client, its volume is set with the "Music" slider.
