Sound card not recognised 4540S

Hi guys !

Thank again for all your hard work !
Lately I reinstalled my system with this how-to : http://www.tonymacx86.com/hp-probook-mavericks/112383-guide-install-mavericks-clover-bootloader.html

But since then I can't have sound working properly on Mavericks. The sound card isn't recognised in my "System Preferences". I also have my EFI partition automatically mounted at launch.. Which is a little bit odd I think (Is it really ?)

Thank you in advance to help me if you have any suggestion on which kext I have to install to make my sound work !

HDA device is not showing up on the PCI bus. Perhaps you don't have it enabled in BIOS.

Man you are just amazing.. So sorry for asking my question, I don't know why but it was that ! Thanks a lot ! I just needed to activate sound in BIOS then relaunch the PBI.

Really, thank you for your work and the quick (and patient) replies RehabMan!
