My sound stopped working all of a sudden. When it happened I was using the sound recorder. When I tried to play one of the sounds back it said something was wrong. I then tried to watch a youtube video, but there was no sound. After that, I tried to play music on spotify, but an error message from spotify said 'there is something wrong with my sound card.'
I found an article on steps to take to restore your sound. I tried a few things. I checked my device manger, and checked the audio driver, and it said it was 'up to date'. Also, when I did the audio troubleshoot it said it couldn't detect any problems. I tried to test the speakers as well, but an error message saying 'failed to play test tone'. I'm not sure what to do now.
I got this laptop in December, and updated to windows 8.1 operating system three weeks ago. That is the only big change I have made. My product number is: E0K79UA
I really need the sound back soon as soon as possible. My math class is based mostly online, and I have to watch a video of teacher for the lesson. What should I do to fix it? Any help is greatly appreciated!
