I was installing the newest version of Microsoft Office Home & Student 2013 and noticed that the tutorial had no audio.
After installation was complete, I had no audio at all on my new HP Envy laptop, whereas I had no problems beforehand.
I get this error message when I try to play a music file: Windows Media Player can't play the file because there is a problem with your sound device, such as a sound card or sound controller. I have nothing connected to the laptop, however. The internal speakers are not muted. There is no sound of any kind coming through my laptop speakers.
