Speaker/Beeper/Buzzer support in Marlin ?

Hi, Having great fun with my Pro C acrylic :-)

Now have auto bed leveling working well with Marlin 1.1.8

A couple questions --- I dont hear anything from the buzzer/speaker --- I can see it's mounted but I've never heard anything from it.

Now, I am partially deaf and higher frequencies are lost on me - so it may be just a case of lowering the frequency - is there somewhere where the frequency is defined ??

Is there a convenient test of the buzzer I can do (an Mcode perhaps) ??

I note that "SPEAKER" is undefined in the config. file --- so I assume it's treated as a buzzer ??
( //#define SPEAKER)
