Отлов звука шагов

Пытаюсь отловить звуки шагов в кс 1.6, но естественно движек не дает это сделать в целях безопасности, читал что есть такая возможность в orpheu, но ничего не получается.

Код:

/* Plugin generated by AMXX-Studio */

#include <amxmodx>

#include <orpheu_stocks>

#define PLUGIN "New Plug-In"

new OrpheuHook:PM_PlaySoundHook
 
public plugin_init()
{
    new OrpheuFunction:PM_Move = OrpheuGetDLLFunction("pfnPM_Move","PM_Move")
    OrpheuRegisterHook(PM_Move,"OnPM_Move")
    OrpheuRegisterHook(PM_Move,"OnPM_MovePost",OrpheuHookPost)
}
 
public OnPM_Move(ppmove,server)
{
    // Retrieves the address of the function to hook
    new PM_PlaySoundAddress = OrpheuGetParamStructMember(1,"PM_PlaySound")
     
    // Creates the function in the module 
    new OrpheuFunction:PM_PlaySound = OrpheuCreateFunction(PM_PlaySoundAddress,"PM_PlaySound")
     
    // Hooks it
    PM_PlaySoundHook = OrpheuRegisterHook(PM_PlaySound,"OnPM_PlaySoundHook")
}
 
public OnPM_PlaySoundHook(channel,sample[],Float:volume,Float:attenuation,fFlags,pitch)
{
    server_print("Sample %s",sample)
}
 
public OnPM_MovePost(ppmove,server)
{
    OrpheuUnregisterHook(PM_PlaySoundHook)
}

Выдает error Код:
