Hello.  So what am I doing wrong here?

 

Map<ChunkCoordinates, ISound> mapSoundPositions = ReflectionHelper.getPrivateValue(RenderGlobal.class, Minecraft.getMinecraft().renderGlobal, "field_147593_P", "mapSoundPositions");
        ISound sound =mapSoundPositions.get(new ChunkCoordinates(xCoord, yCoord, zCoord));
        if (sound != null) {
            HashBiMap<String, ISound> playingSounds = ReflectionHelper.getPrivateValue(SoundManager.class, SoundManagerInstances.soundManagerInstance, "playingSounds", "field_148629_h");
            String soundString= playingSounds.inverse().get(sound);
            SoundManagerInstances.soundSystemInstance.stop(soundString);
        }

 

There is definitely a sound at the coordinates but the "sound" is always null.

Hi

 

Have you tried putting a breakpoint at the ISound line and inspecting mapSoundPositions?  Should show you pretty quickly what's wrong.

Good idea, I'll give it a try.  I actually changed my code to stop with an identifier cause I couldn't get this to work, but I'll get back to it in a bit as I would prefer not to have to keep track of the previous sound manually.
