Beeper slide bar?

Basic Information:

Printer Model:
MCU / Printerboard:
Host / SBC

Does anyone know what the Beeper volume slide bar is suppose to do under Miscellaneous. My beeper is not working at end of print or colour change, its annoying. If I turn up the slider the beeper just starts and never goes off. (SV06 Klipper with mainsail on a laptop)

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
