My audio randomly stopped working a few days ago. I use a Windows 7 laptop. Neither the headphones nor the internal speakers will play any sound from videos or any other audio I've found. ALTHOUGH when adjusting the "Speakers / Headphones:" icon for its audio level, I hear a ding so I know they're capable of playing some sort of sound. Very confused on the issue if anyone can help me! If you have suggestions or questions in route to a solution please share them!
Seeing as Internet Explorer does work i'll put this as an answer.
If you have the Google Chrome Toolbox installed you can mute all tabs by pressing Alt+W. To un-mute you can press Alt+W again.
You can also click the colored gear and choose "Unmute all tabs".
If you don't have the Chrome Toolbox installed or the method above doesn't work there is also a small possibility you muted the audio of Chrome in the Audio Mixer of Windows.
click the audio-icon and choose "Mixer" and pull the slider up for Chrome:
THIS FIX IS FOR WINDOWS 7 AND CHROME
FOR STEP 5 YOU MUST HAVE A VIDEO PLAYING!
