"No output device found" no sound

Im running a ASUS H170M-E D3 motherboard which has on-board audio (Realtek ALC887) with speakers plugged into it. I used the Unibeast / Clover/ Multibeast install guide and after a few hiccups, most things are working. The exception being audio. I tried installing the drivers with Multibeast, I didn't get an error, but sound still says "No output device found". I've seen links to web-drivers for the audio (audio_cloverALC-110_v1.0r10.command), but when I use them, it says:

EFI partition...
