VEVOR 165.1 mm in Ceiling Speakers, 150-Watts, Flush Mount Ceiling & in-Wall Speakers System with 8ΩImpedance 89dB Sensitivity, for Home Kitchen Living Room Bedroom or Covered Outdoor Porches, Single

I’m trying to use the aux function of the 645bt speaker but it doesn’t seem to work Is there a special 3.5mm cable that needs to be used I have tried some I have at home but no sound is coming out of the speaker. The Bluetooth function is working correctly
