No HMDI/Speaker Audio, only headphones

Audio works when headphones are plugged in. Once removed, the device continues to say ‘unplug headphones to connect’ to either Bluetooth, or HMDI. No sound comes out of the speakers when handheld. No water damage, only used headphones once this problem happened to see if it would ‘reset’ once actual headphones had been unplugged. What caused this and how do I fix it?
