After updating to 1.21.7 I obtained the lava chicken music disc from a chicken jocky and played it in a jukebox.
The jukebox displayed the floating notes particles but the actual sound was not playing.
Other music discs work just fine.

Same, It works for my friend but not me. Unsure why since I did a full re-install of Minecraft and logged out, logged back in my Microsoft account. Even did it in a creative world and that is the only disc that does not work.
