TOPIC: How do I fix this???

Ok so for the past hour I've been having this sound problem and when I try to troubleshoot it it says error.
Please someone tell me how do fix it!
Here's what it looks like and no I didn't mute the sound, because when I click on the little sound icon it just starts troubleshooting. prntscr.com/juv7el

Update your drivers

unplug and plug the headphones you have. after that try using other headphones, if that doesn't work you'll know it's a problem with the hardware.
