Ok I will start from there to see if I can get audio. So did you successfully gain audio on your HP 4540s/4530s on El Capitan? And thats what you did? Thanks.

Hello, I followed the guide to installing El Capitan step by step and everything works fine except audio. I followed RehabMan's guide. I also followed this:

"Audio: After installing new/updated kexts or after the initial installation, you may lose audio.

To fix:
- reboot without caches (hit space at Clover, select without caches)
- rebuild cache
Code (Text):

sudo touch /System/Library/Extensions && sudo kextcache -u /

- reboot normally (if needed, two times)"

Still no luck. Can anyone help? I would greatly appreciate it! Thank you.

You did not include a model specific SSDT in ACPI/patched. Use install_acpi.sh as per guide.

@RehabMan Thanks for the reply! So all I have to do is run that command in terminal and I should be good? Or follow the process all over again?

I didn't check anything else... I only checked ACPI/patched for the expected files and found the model specific SSDT missing.

I'm running ProBook 4440s, and I have Audio no problem, even in macOS Sierra it's perfectly fine. Since you have a 4540s, it's basically the same internals just bigger chassis. Run ./install_acpi.sh to install all ACPI files to your EFI/CLOVER/ACPI/patched folder, but make sure you choose which model your installing (eg. './install_acpi.sh install_4x40s' for my specific laptop.), and you should be good after booting without caches, rebuilding per the guide and rebooting again, possibly twice if necessary.
