VoodooHDA 3.x

[deeveedee]

I just discovered that the keyboard Volume controls on my HP EliteBook 850 G7 work for increasing, lowering and muting audio with VoodooHDA.kext 4.0 in macOS Tahoe 26.5.1.  The pleasant surprises with VoodooHDA.kext keep coming.  Well done, Devs!

of all IDs, why 80? does it represent yours or auto detect?

Auto detect will be zero.

thanks for the info brother.

If set to zero, it'l fallback to old function aka traditional?

Approximately, but the development is not finished yet. If you don't want AMD HDMI audio then you can use version 3.0.5 Traditional. It's perfect.

I haven't yet had a chance to test UniversalHDA.kext.  I feel a loyalty to VoodooHDA.kext which has served me well, so I'd only want to switch to UniversalHDA.kext conditional on the following:

1. Is UniversalHDA.kext the "next version of VoodooHDA.kext" and thus replacing VoodooHDA.kext?
2. Will VoodooHDA.kext eventually be providing support for Intel iGPU HDMI (not just AMD dGPU HDMI)?  If not, does UniversalHDA.kext provide support for Intel iGPU HDMI?

1. AFAIK yes.

2. I think no. AppleGFXHDA provides support for some Intel iGPU but we didn't have attempts to make such audio. Dunno about UniversalHDA.

 

I am busy last week but the VoodooHDA is not finished yet and I planned to continue. The purpose is to make AMD HDMI stable and appropriate for more AMD cards. More than AppleGFXHDA can.
