i use a raspberry pi 3 with raspbian stretch OS. its audio output has been worked until i check it yesterday and it didn't have sound. i use a headphone and want to listen music through 3.5mm jack but i don't hear anything. i also use a usb adapter but it was the same as jack output. i don't know why it suddenly stops working. i force the audio output to jack from "raspi-config" and i also run this command :
amixer cset numid=3 2
but that doesn't help. could somebody help me?
thank you
