OLED library doesn't work with sound

my code is using keypad library and oled display and piezo element. Without the oled code added everything works just fine. as soon as I add code for that, sound stops working. doesn't even call the display oled(). I added several print statements to check this.

#include <Wire.h>                                                              
#include <Adafruit_SSD1306.h>                                                   
#include <Adafruit_GFX.h>                                                       
#define OLED_WIDTH 128#define OLED_HEIGHT 64                                    
#define OLED_ADDR   0x3C
Adafruit_SSD1306 display(OLED_WIDTH, OLED_HEIGHT);

void setup(){
 display.begin(SSD1306_SWITCHCAPVCC, OLED_ADDR);
 displayOled(); //welcome screen //stops here and crashes everything setupNewGame();
}

void loop() { 
  char guess = 'n';
  String result = "miss";
  boolean isAlive = true;
  while (isAlive){
    guess = getGuess();
    if (guess != 'n') {    
      Serial.print("You guessed:");
      Serial.println(guess);

      result = checkYourself(guess);
      Serial.println(result);
      playSound(result);
      if (result.compareTo("kill") == 0) isAlive = false;
      Serial.println("Enter a new guess (1-8):");     
    }
  }
  setupNewGame();
}

my display OLEd function:

void displayOled() {
  display.begin(SSD1306_SWITCHCAPVCC, OLED_ADDR);

  display.clearDisplay();
  display.setTextSize(2);
  display.setTextColor(WHITE);
  display.setCursor(20, 0);
  display.println("WELCOME");

  display.setTextSize(2);
  display.setTextColor(WHITE);
  display.setCursor(0, 17);
  display.println("PressENTER");
  display.setCursor(0, 35);
  display.println("to start!");
  display.display();
}

Is the library causing this? please help thanks

From your code you are trying to run the OLED by its self or you are missing other code.

Anyways, what did you get when you ran the I2C scanner with all the devices hooked up? Did you get the correct number of I2C devices found?

yes found it at 0x3C
my oled works perfectly fine without sound function. But with sound it stops everything at setup where displayoled() is called
