Many of the new sound events in 1.21 do not match their Java Edition counterparts. This is a departure from the precedent set in 1.20.40 and 1.20.50, where all new sound events used the correct names and definitions that aligned with Java Edition. This affects commands such as those used in Marketplace maps. Controlled by sound_definitions.json.

In addition, some sound events have different pitches or volumes used for their sounds. This causes them to sound different when played in-game AND with commands. Controlled by sound_definitions.json.

Finally, some sound events are implemented differently than Java Edition. They sound the same when played with commands, but different in-game. Controlled by sounds.json and sound_definitions.json combined, or by the entity's entity.json file in case of the Breeze.

See table below. Note the [MISSING] does not mean the sound is silent in-game; it means there is no corresponding sound event in Bedrock Edition. Thus, these sounds cannot be controlled separately in Bedrock, unlike Java.

This report covers sounds from 1.21.0-1.21.40. For 1.21.50 sound events, see MCPE-187380.

Additional Notes:

• As stated above, [MISSING] does not mean the sound is silent in-game; it means there is no corresponding sound event in Bedrock Edition. Thus, these sounds cannot be controlled separately in Bedrock, unlike Java.
• Breeze sounds have multiple issues due to their implementation through breeze.entity.json. See MCPE-180023 for details on the idle sound and MCPE-180029 for the whirl sound. Other sounds, such as hurt and death, are configured incorrectly in sounds.json.
  • The mob.breeze.charge sound is duplicated in sounds.json and breeze.entity.json. (charge is not a valid sound call in sounds.json)
  • The mob.breeze.idle_air sound never plays (ambient.in.air is not a valid sound call in sounds.json)
• 1.21 block sound implementations are incorrect across the board. Java Edition uses consistent break, fall, hit, place, and step configurations when calling any block sound, matching this table (from the "stone" page on Minecraft Wiki). These pitches and volumes apply to all block types except metal, anvil, and turtle_egg:
  • This issue is not new to 1.21, but that is outside the scope of this report. All block sound sets added from 1.16 onward are affected.
  • 
• Block sounds do not follow any consistent convention, as seen in the table:
  • Trial Spawner/Vault: [block_name].[action] — Break, Fall, Hit, Place, Step + Unique sounds
  • Copper Bulb: [action].[block_name] — Break, Fall, Hit, Place, Step
  • Copper Bulb: block.[block_name].[action] — Turn Off Turn On
  • Tuff Bricks: [action].[block_name] — Place, Step only
  • Heavy Core, Copper Grate: [action.block_name] — Break, Step only
  • Java Edition always follows block.[block_name].[action] — Break, Fall, Hit, Place, Step + Unique sounds
• The issues with Wind Charge and Breeze Wind Burst sounds are detailed here: https://bugs.mojang.com/browse/MCPE-180027
• Although music plays more often on Bedrock Edition than Java Edition, that was not considered for if a music event implementation matches Java Edition. The only qualifications for a music event being implemented correctly are:
  • Song list matches
  • Volume matches
• Crafter sound events both remain incorrect in 1.21.20.21. The randomization between pitches 0.96, 1.0, and 1.04 should happen in the sound event; the event call in sounds.json should still use pitch and volume 1.0.
• The Copper Door open sound event is more incorrect in 1.21.20.21 than previously. There should be entries of toggle2 and toggle3 with pitch 1.0 and pitch 1.1, copied from Java Edition.
• Many block sound pitches and volumes are still incorrect in 1.21.20.21, in particular:

• • Hit sounds should use a 0.25 volume
  • item.use.on should use the place sound, not the step sound (since it is used for placing a second slab on a block)
  • The 1.2 pitch-up on polished tuff should be handled in sound events, not event calls in sounds.json
  • Normal tuff and tuff bricks have multiple incorrect volumes
  • Trial Spawner and Vault are missing item.use.on
  • Copper still has randomly varied pitches on breaking and placing sounds
  • Step and fall sounds are completely wrong in pitch and volume across the board
  • Heavy core and cobweb sounds were missed entirely
  • Copper door open event call varies from [1.0,1.1] instead of [0.9,1.0]
  • Copper door close, as well as both copper trapdoor sounds, are missing the [0.9,1.0] pitch variance
• Bundle sounds (excluding insert_fail) need to randomly vary in pitch in sounds.json between to match Java Edition
• Mob spawner sounds are in the wrong folder (mob_spawner instead of spawner)
