    I’ve tried numerous fixes and none seem to work. Since I can use Bluetooth, I don’t care about the internal speaker per se. However, as a radio deejay, I do need headphones output to connect my laptop to our control board. So I ordered a Behringer USB audio interface, which is inexpensive and simple to use. It has RCA connectors for wired speakers and a phone connector for the headphones jack.
