Regarding sound, I pulled an extreme noob move and won't even go into it... ha.
Regarding the dual monitors not working, I actually pulled my GPU out and I'm using the built-in iGPU...
Edit: Something interesting... After I wake my computer from sleep, the right monitor (non-working) shows the white apple but blurry and distorted and then the monitor shuts off again when the left (working) monitor wakes up.
Please post your EFI folder and a screen shot of what is in your /Library/Extensions/ folder.
Also, which version of macOS are you running?
