So the sound randomly just went away from my computer and no matter what I do I can't get any sound. I have my computer connected to my tv via that black wire that gives sound + video. I think it's called HDMI , not sure though.
When i look it has the speaker icon with a red X next to it and when i hover my mouse over it it says "No speakers or headphones are plugged in."
I also have some speakers that when I plug into my computer get no sound. But the speakers, they turn on fine. When I plug in my headphones directly to my computer they also don't work .
My soundcard is : NVIDIA High Definition Audio
My os : Microsoft Windows 7 Professional Edition Service Pack 1 (build 7601), 64-bit
