I had an issue with Windows update and thru help from Microsoft I had to do a system restore to get computer running again. Now my external speakers, that I have used for many years, do not work, I hooked up new external speakers, but still have the red X next to the speaker icon on task bar. When I went into devices, it does not show any speakers listed. When I unplug the speakers from the computer, I could hear a sound, so it appears to be something with my monitor not talking to my computer telling it that speakers have been added. I have worked on this for a couple of days. How do I add the external speakers, if that is what I need to do to get external speakers working???
