Expected result:
Player inserts music disc into Jukebox.
Game reduces or stops background music (as happens in LCE and Java editions).
Jukebox plays music disc and user can audibly hear music disc.
Actual result:
Player inserts music disc into Jukebox.
Game does not reduce or stop background music.
Jukebox plays music disc alongside the game’s background music, and the user cannot really audibly hear music disc.
Please see video for more context. You can just hear the music disc playing, along with seeing visual queues that reinforce the disc is playing.
It would be helpful if someone could link to the duplicate issue because I can't see it when logged into Mojira
