This is an audio driver issue and I'm currently having the same sh** today. It's either audio driver is malfunctioning or the built in sound card chip in the motherboard is not working properly. The solution for that is either:
- uninstall and reinstall audio driver
- updating driver
- and tweaking the audio settings like enhancements, device, etc.
You can see everything on device manager, it's working for others. For me.. different story. Looks like I need to by a new separate sound card to solve this issue.
To get into device manager, just hit the windows key and search device manager. Find the "sound bla bla bla" there and check the drivers installed in it.
