Ignoring subsequent pulses from IR remote while key is held down

6v6gt:
You may have more success using millis() instead of delay() like in this example code (untested).
It will not, however, be compatible with any delays you have elsewhere in your code.

unsigned long inMuteMs = 0 ;

. . .
. . .
void loop() {
  . . .
  . . .
  //MUTE

if (results.value == 3772837903) {
    //remote button MUTE
    if ( millis() - inMuteMs > 1000 && inMuteMs != 0 ) {
      // abandon old mute attempt
      inMuteMs = 0 ;
    }
    else if ( millis() - inMuteMs > 500 && inMuteMs != 0 ) {
      // valid mute
      results.value = 0;
      analogWrite(LED, LEDon ? LOW : volume); //Turn the LED on or off, depending on if ledOn is true or false
      LEDon = LEDon ? false : true; //Toggle between false and true
      inMuteMs = 0 ;
    }
    else if ( inMuteMs == 0) {
      // start of new mute attempt
      inMuteMs =  millis() ;
    }
  }
  . . .
  . . .
}

Thanks, this may be the direction I need to take. I studied millis() earlier today but the Arduino page I looked at implied it was only for determining elapsed time. I'll see if I can dig deeper.

Meanwhile I tried your code. The good news is it ran first try. Buy it's not quite there. When I hold the Mute button down for an extended period of time, it flashes my Pin 9 LED every 500 mS. That would be acceptable except that it does not respond to a short tap of the Mute button Longer presses yield unpredictable results. So I find myself having to use short and long presses to toggle the LED on and off.

I'll dig into your code to see if I can understand how it works. I'm new to this and dyslexia doesn't help, especially when trying to keep track of toggle states.
