No success 4) Stop/Start Windows audio service. No success 3) try to restore to an earlier configuration. No success 2) Uninstall ALL audio software and drivers, reinstall everything from manufactures websites. This is what I have tried: Obvious first step for me was to reinstall the audio drivers. Two days later, after searching through hundreds of forum threads and finding that this problem is actually fairly common, I still have not found a solution. I don't quite understand this contradiction. In device manager, all audio devices are installed with current drivers and all are 'functioning normally'. Open volume mixer and 'No audio device is installed'. Open playback devices and all are enabled and 'working'. Little white x on the speaker icon on taskbar, mouse over it and it displays my current audio device and volume 0. So suddenly one day the audio on my system just disappears.
