something like this?

#include <M5Stack.h>
#include "utility/M5Timer.h"

char currentCharEffect = '\0'; // none
int currentVolume = 0; // OFF

M5Timer M5timer;

void playWAV (char effect, int volume)
{
  ...
}

void playCallback() {
  playWAV(currentCharEffect, currentVolume);
}

void setup() {
  M5.begin();
  M5timer.setTimeout(5000, playCallback);
}

void loop() {
  M5timer.run();
  // here some code modifying currentCharEffect and currentVolume
}
