<![CDATA[Background noise]]>Does anyone knows how to silent the digital background noise from the loudspeaker without cutting the speaker wires? Sketch alarms should still be audible.

dacWrite (25,0);

there will still be a tiny sound, but barely audible

dac = machine.DAC(machine.Pin(25))
dac.write(0)
