When I first installed Windows 10,  I had no audio at all and with Microsoft Community support I solved it soon.But one problem remained since then. When the laptop speaker works, ear phone would not work and when ear phone is made to work, the computer speaker wont.  And I have not been able to solve it ever since despite various suggestions. Any help?
