As it turns out, noTone() and tone() are in the core arduino API, but seemingly not implemented for the Arduino Due.  I was hoping to use tone() and noTone() to implement the mario death sound found here, but when I add the code and compile it, I get the following errors: 
trenchRun:154: error: 'tone' was not declared in this scope trenchRun:156: error: 'noTone' was not declared in this scope
In case you're interested, here's an SSCCE, compiled against Arduino 1.5.4 on Mac OS X 10.8:
void setup() {
  // put your setup code here, to run once:
}
void loop() {
  tone(1, 12345, 1000);
}
sketch_oct24a.ino: In function 'void loop()': sketch_oct24a:7: error: 'tone' was not declared in this scope
Since I have an Arduino Due, I am limited in using Arduino 1.5.4.
How do I implement the tone() and noTone() functions for the Due?
