Information regarding sound playback

[WizzardMaker]

I already RE a bit of the sound system

The "PlaySound" method is at S4_Main + 0x10C390
Arguments seem to be:

arg1(ecx) - SoundSystem*
arg2(esi)  - Debug related string - seems to be always nullptr
arg3 - Sound Id
arg4 - possibly volume
arg5 - sound effect panning maybe (A high value played a sound on the right channel) - seems to point at the first variable in the SoundSystem struct
arg6 - Again a pointer to the SoundSystem*
arg7 - Unknown, seems to always be 0

The global SoundSystem* is at S4_Main + 0x10540C4

Other findings regarding sound and music:

MusicVolume = (DWORD*)(S4_Main + 0xDB596C);
MusicToggle = (DWORD*)(S4_Main + 0xDB5978);

SoundVolume = (DWORD*)(S4_Main + 0xDB5984);
SoundToggle = (DWORD*)(S4_Main + 0xDB5990);

SetMusicVolume Method at S4_Main + 0x10C4A0
SetSoundVolume Method at S4_Main + 0x10C500
Both need a reference to the SoundSystem* at 0x10540C4 on ecx.

Sound Ids that I've found:

//UI:
BUTTON_CLICK = 7;
BUTTON_RELEASE_NOT_ACTIVATE = 6; //Happens when you move away from a button without activating it
//Ingame:
HAMMER_HIT = 5;

Variations of Sound Effects are baked into an ID, with 5 being a good example. Playing the same ID multiple times gives different sound samples of the same type

Okay, just found out about every ID. Clear names are at S4_Main + 0xC15374
