This is exactly what System Restore is for. Some folk don't know about it so a link follows.

So I have a Lenovo Yoga 2 13, and all of a sudden, the sound dropped very low overnight somehow. Even when I turn volume on 100% using the keys and system, it's so quiet I can't hear the words on a show I'm watching. I have the volume turned up to max everywhere. However, when I go to playback devices from the speaker icon in the lower right hand corner, and go to properties, and from there go to advanced and press test, the sound is very loud, as it would normally be. I checked Netflix for the sound and it is turned all the way up. I even checked on other apps like iTunes or YouTube to see if the problem persisted, and the sound continued to be very low. Any help?
Thanks
