Audio not working Probook 4540s

Hey I have installed OSX Yosemite following

http://www.tonymacx86.com/hp-proboo...-install-yosemite-hp-laptops-clover-uefi.html

I have followed and completed the guide without any trouble, but i have realised that the audio is not working. In osx it's saying there is no input or output devices found. everything else is working perfectly, wifi, trackpad, graphics ect. I do not know where or how i have gone wrong. i can not find anyone else in the same situation as me, any help would be appreciated. should i try a fresh reinstall?

How did you manage to make the Wi-Fi work? And also the trackpad?
Btw I also have Probook 4540s


Here's your solution:

14. If you can boot and you don't have sound:
- repair permissions in Disk Utility.
- restart.
- boot without caches
- rebuild cache with kext wizard
- reboot 2x

If you follow the guide, both work.

How did you manage to make your Wi-Fi and trackpad work?? That's my last few fixes... I can't understand the one in the guide Can you help me? Probook 4540s core i7

WiFi requires compatible hardware. Compatible hardware is listed in... wait for it... the guide.

As for trackpad, follow the guide and be sure to do an EC reset (as is mentioned in... wait for it... the guide).
