Has anyone else noticed that commenting out # Define speaker does not disable the buzzer?
I found this on an Ender 5 with stock board.
Present in both Marlin 1.1.9 and Bugfix 1.1.x
This issue played havoc with my BLtouch on pin 27 until I scoped it and saw the buzzer was still sending beeps on pin 27.
Now I'm looking for a better way to disable buzzer on pin 27.... any ideas?
Thanks
Ray

No no no, let me explain.
The pin27 board cuts the buzzer out of circuit.
It's the firmware which still produces the tones signal.
I tried this with an un modified board.
The buzzer makes beep sounds with the line enabled and disabled...
The define_speaker function seems to have lost its control over the normal tones produced, like store eprom which emits a long beep etc.

I was thinking about doing this though it requires the removal of the buzzer and installation of a audio amp circuit and a speaker.
A buzzer is not a speaker and cannot operate as a speaker the buzzer only buzzes at its designed specifications and no other tones...
