In short, incompatible switches will make inconstant voltages to run through the it, thereby causing buzzing noise.
The cause is almost always a compatibility issue between the dimmer and the led’s driver (power supply).

The pot lights are from costco.
While most led lights are dimmable, a common complaint is hearing a hum or buzzing sound coming from the bulbs when they are dimmed.
