A family member who shares this PC with me Downloaded a program last week so we could watch TV on our PC but after I couldn't use the volume control because this program took control of it and we couldn't use it. I Found what I thought was a way of fixing this but all I ended up doing was turning off the speakers. Now we have no sound at all. How do I turn my speakers back on? I know I should have let him fix this but his way of working the control was way to complicated for me to use so I got mad and tried to fix it myself. Please can you help me. If he finds out what I did I'm in BIG trouble.I clicked on to Control panel, clicked on hardware and sound then to sound then to manage audio devices then went to playback and under the headphones with the word called Realtek HI definition audio next to them went to properties and hit uninstall.Now I have NO sound at all. what do I do to fix this?
