Buzzer sounds strange after connecting display and ir diode

Using Arduino Audio

ok I kind of solved this problem. I changed the playSong function to the following:

void playSong(int currentSong){
  Serial.println("playing");

  TIMSK1 = 0;   // turn timer for ir interrupts off initially
  
  delay(200);
  

  for (int i = 0; i < songs[currentSong].totalNotes; i++)
  {


    TIMSK1 = 1;                                         // before every note check for 6.7 milliseconds if any button is pressed, if so stop playing
    IrReceiver.begin(RECEIVER, ENABLE_LED_FEEDBACK); 
    unsigned long startMicros = micros();
    while (micros() - startMicros < 6700) {
      if (IrReceiver.decode()) {
        Serial.println("received ir while playing");
        play = false;
        IrReceiver.resume();
        return;  
      }
    }
    TIMSK1 = 0;



    const int currentNoteLeft = songs[currentSong].notesLeft[i];
    const int currentNoteRight = songs[currentSong].notesRight[i];
    float wait = songs[currentSong].durations[i] / songs[currentSong].speed;

    if (currentNoteLeft != 0 && currentNoteRight != 0) 
    {
      play2Notes(buzzerPin1, buzzerPin2, currentNoteLeft, currentNoteRight, wait); 
    }
    else
    {
      if (currentNoteLeft == 0){
        if (currentNoteRight == 0 ){
          noNote(buzzerPin1, wait);
        } else{
          playNote(buzzerPin2, currentNoteRight, wait);
        }

      } else {
        playNote(buzzerPin1, currentNoteLeft, wait);
      }
      
    }
  }

  play = false;
  IrReceiver.begin(RECEIVER, ENABLE_LED_FEEDBACK); 

}

(im using version 4 of the ir remote library now. it claims to be faster.)

so now, before every note, i only check for a very short amount of time if a button is pressed. if so, the song stops playing.

to do that im only turning on the timer1 (usually the ir library uses timer2 i think, but i changed it to 1) before every note and wait for ir signals for 6.7ms. i dont know why, but I also had to call the IrReceiver.begin function again after turning off the timer. stopping the song can take a few seconds if there are long notes, but it works.

if there is a better solution, hit me up pls.
i dont know if there is one, but if the tone library claims to be compatible with the IR receiver...
