Missing chatter bits and stack corruptions

[JohnnyonFlame]

Hello,

Found your solution while checking out the status of fmod1.x for aarch64 - this function is wrong and will cause major graphical corruptions, missing sounds and other brokenness - you want to change this to FMOD_Studio_EventInstance_SetParameterByName instead.

I ended up with a solution that is a tiny bit less intrusive and avoids patches:

// TODO:: should probably be taken from fmod.h...
#define FMOD_VERSION 0x00020206
#define DECLSPEC __attribute__ ((visibility("default")))
DECLSPEC int _FMOD_Studio_EventInstance_SetParameterValue(void *system, const char *name, float value)
{
        extern int FMOD_Studio_EventInstance_SetParameterByName(void *, const char *, float, int);
        return FMOD_Studio_EventInstance_SetParameterByName(system, name, value, 0);
}

DECLSPEC int _FMOD_Studio_System_Create(void *studiosystem, unsigned int headerversion)
{
        // Override the FMOD_VERSION header.
        extern int FMOD_Studio_System_Create(void *, int);
        return FMOD_Studio_System_Create(studiosystem, FMOD_VERSION);
}

which can be used with the following config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<dllmap dll="fmod" os="linux" target="libfmod.so.13"/>
	<dllmap dll="fmodstudio" os="linux" target="libfmodstudio.so.13">
