Call to noTone() without first calling tone() fails

It would be nice if this was handled gracefully. Thanks!

#include <Tone32.h>

#define BUZZER_PIN 16
#define BUZZER_CHANNEL 0

void setup() {}

void loop() {
  noTone(BUZZER_PIN, BUZZER_CHANNEL);
  tone(BUZZER_PIN, NOTE_C4, 500, BUZZER_CHANNEL);
}
