ALC 280 - HP Elitebook 840 G2

[jdl123]

Specs are as follows -

HP Elitebook 840 G2 Laptop
I7-5500u
Intel HD Graphics 5500 (iGPU)
Radeon R7 M260 Dedicated
8GB RAM
Realtek ALC 280.

Cannot for the life of me get the audio to work! Fairly new to all this, tried AppleALC, VoodooHDA etc. When loading Clover EFI and I do the sound test it shows the ALC 280 speaker output and plays the chime fine. However soon as I get into 10.15.5 Catalina it doesn't show any audio devices etc. I've tried changing ID in config.plist in Clover Configurator and still nothing.

Can anyone help? Will post plist config etc.
Let me know what else you need?

Many thanks.

Thanks! do I need to enable them in the config.plist? should I also be using AppleALC rather than voodoo or vice versa? quite confusing....

tyvm for your help!

yes

should I also be using AppleALC

yes, use AppleALC, remove VoodooHDA

When you say remove the #s how do you mean? I can’t see a #s to remove or am I just being stupid

here you go removed # ok try make sure to remove voodo.kext and replace with AppleALC

 

[jdl123]

Okay so I replaced config.plist with your one, removed voodoo kext and replaced with AppleALC, also tried all layout ID's and still no output devices. Am I missing something? Don't know what else to try?!

is your HDMI sound working the only thing I can think of is to patch DSDT https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

So in Clover it picks up Realtek ALC280 as startup sound and plays the test tone. But soon as I get into Mac it doesn't pick anything up

This is the config in clover
