#define BEEPER_PIN 61

to

//#define BEEPER_PIN 61

@fbarcenas What kind of LCD? Does enabling SPEAKER allow you to play musical tones?

@jbrazio Sounds like a crappy debouncer. Previously the delay in the beep() function helped ensure that "flaky" buttons wouldn't have this problem. (Which they all are on these units - the on/off state "flickers" when you press them.) To address this, we need to either put the delay back into lcd_quick_feedback or make a more reliable debouncer.

@fbarcenas Try this…

  void lcd_quick_feedback() {
    lcdDrawUpdate = LCDVIEW_CLEAR_CALL_REDRAW;
    next_button_update_ms = millis() + 500;

    #if ENABLED(LCD_USE_I2C_BUZZER)
      lcd.buzz(LCD_FEEDBACK_FREQUENCY_DURATION_MS, LCD_FEEDBACK_FREQUENCY_HZ);
    #elif PIN_EXISTS(BEEPER)
      buzzer.tone(LCD_FEEDBACK_FREQUENCY_DURATION_MS, LCD_FEEDBACK_FREQUENCY_HZ);
-   #else
-     delay(LCD_FEEDBACK_FREQUENCY_DURATION_MS);
    #endif
+   delay(LCD_FEEDBACK_FREQUENCY_DURATION_MS);
  }

i use VIKI 2

Yes i can play musical tones.

Yes i can play musical tones.

Uncomment #define SPEAKER for best results. I believe that if you insert the suggested delay in lcd_quick_feedback the button will be more reliable, and the click sound will work.
