My external speakers have stopped being recognised overnight. I even bought new speakers and they have they same problem. They are Logitech Z200 and connect to the headphone jack.
When I go to the Playback tab in the Sound part of the control panel, the speakers do not appear. I have tried earphones using the same jack on my PC and they work fine. In device manager I don't find any new drivers when I search online for them. Any suggestions would be appreciated.
