It means that everything is being forward to a BT headset. You need to disable it, go to the BT icon, My devices, choose the BT that is currently connected and tap on Disconnect, or just power off the BT.
SOURCE: my sony dav-s-400 system keeps activating headphone port output.
Just had and fixed the same problem that hundreds of people are suffering with this system!!
Sony DAV s400 - same problem, won't play though speakers and display
indicates that headphones are plugged in - when they are not. Fairly
easy to fix and took me less than an hour from start to finish:
1) Remove top cover
2) Remove circuit board that has Audio In/Out phono scockets (to get access to Amplifier Circuit Board)
3) Remove Amplifier circuit board (has the speakers attached)
4) Turn it over and remove copper heat shield
5)
Resolder joints where the big brown capacitor is and where the wires go
to the front headphone socket...and any other dodgy joints that you
find
6) Reassemble.

Try changing the Windows Default Audio devices
Hopefully this will work
