I have solved the problem myself.
If you are only getting mono sound to your headphones from your Galaxy Tab 3 8 inch, stereo may come back if you do a soft reset.
However, if you do not want to risk losing other settings, do the following:-
Go to Settings/System/Accessibility/Hearing/Mono audio
Look at the check box and if there is a tick in it, tap to clear it.
You should then have full stereo again.
The Mono audio mode is for use with a single earphone.
The process does seem a bit more complex than it should be to switch between stereo and mono sound!
