I have my computer playing audio through the 1/8" audio jack connected to a yamaha amplifier then to my speakers. A few days ago I had some Idiot cross some speaker wires with a screw driver. Right after he did that there was a loud pop and my computer shut off. usually it would just put the amp into protection mode but this time it didnt. It took a while for the computer to turn back on but when it did, the realtek hd audio manager has completely dissapeared and I cant find it anywhere. the sound doesnt work through my laptop speakers or audio jack. so i tried uninstalling the drivers, restarting, reinstalling them and a bunch of other stuff but nothing is showing up. the only playback devices are my tv through my hdmi cord.

Laptop: Asus x550L with windows 8.1
