Speakers Suddenly Stop Working?

[HES]

So I powered my SP4 up today and noticed...I have no sound. I use the trouble shooter and it says no sound devices (headphones, etc..) attached. I've tried running the troubleshooter to no avail. Has anyone experienced this? Any ideas on how to get the speakers to work again?

check that the audio drivers are installed and working in the device manager. you can also check the event logs (in Cortana, type event logs)
