Just wondering if anyone knows if there is a way to get my Realtek HDA ALC295 layout 31 audio to work with AppleHDA and AppleALC? It works with VoodooHDA, but without output to HDMI. Without Voodoo I have tried injecting ID 28 and 3 and 1 but in all cases no output device is detected.

Still very much a newbie however I have managed to get the HD620 graphics and backlight to work and patched the DSDT to get the battery status and trackpad to work properly (thank you to Rehabman) - just audio to sort. Any help gratefully appreciated.

layout-id 31 is not valid with AppleALC.

Thanks for the quick response. Anything I can do? Do I need to edit a Kext ?

Obviously, you need to use one of the supported layout-id values.
 
Apologies for asking stupid questions but do I do that just be injecting any supported layout ID in clover as per your example plists ?

There are many ways to do it (config.plist/Audio/Inject, config.plist/Devices/Properties, ACPI _DSM, config.plist/Devices/AddProperties, config.plist/Devices/Arbitrary, and even AppleALC kernel flag alcid).

If you are using a guide plist, you inject it via config.plist/Devices/Properties. You will see it there but it is commented out.
 
Hi Freeskam, I have the same laptop as you and i could'nt get my battery status to work, would you please share with me your DSDT patch for battery

PLEAAAASE!!
