In 1.6.4 it was easy to add sounds using the SoundLoadEvent and SoundManager; java docs in 1.7.2 still maintain that SoundLoadEvent is a 'good place for adding your custom sounds to the SoundPool', but there doesn't seem to be any way to access the sound pool using the SoundManager.

 

Anyone know how it works now?

As far as adding sounds go you do it via json file: http://www.minecraftforge.net/forum/index.php?topic=15406.0

 

You can't do a whole lot with sounds yet though,

 

Currently these events are never posted:

PlayBackgroundMusicEvent, PlaySoundEffectEvent, PlaySoundEffectSourceEvent, PlaySoundEvent, PlaySoundSourceEvent, PlayStreamingEvent, PlayStreamingSourceEvent, SoundEvent, and SoundResultEvent

 

SoundLoadEvent and SoundSetupEvent are posted to the forge event bus in SoundManager

Thanks, that's all I needed to know!

I'd say SoundLoadEvent is deprecated. A hook into SoundHandler would be better.

I agree. I just removed my SoundLoadEvent listener entirely, given that sounds are loaded automatically from a .json file now there seems to no longer be any use for the SoundLoadEvent.
