[HELP] How can I enable HDMI audio with NVIDIA GTX 750Ti?

Hmm... Don't know why it's not working for you. I used the same method to get HDMI audio from my GTX 745.

This is the method that is detailed in the HDMI audio guide.

Ok, thanks.
I will see that guide soon.

I tried voodoo HDA + Clover ALC(RealtekALC.kext) and it works but cannot adjust volume.
Do you have any method to adjust volume?
I tried sound flower bed. but it cannot save settings it will set as default after reboot.
Thanks for helping.

I would only use VoodooHDA as an absolute last resort. Trying to use both VoodooHDA and Clover ALC together is a bad idea.

But if I only use voodoo HDA then I cannot get line-in and internal sound output.
if I only use clover ALC then I cannot get HDMI output.

I'm not a fan of VoodooHDA. I said, I would only use it if nothing else works. But it's your choice.

I agree with pastrychef on this ..VoodooHDA should only be used a a last resort, its not that well maintained or supported which i why i've always avoided it ..... there are much better methods for patching AppelHDA such as Toleda's work and AppleALC.

You can not adjust the volume of any HDMI device from MacOS ... this is completely normal ... HDMI audio in MacOS is treated as a digital passthrough to a DAC within the target HDMI device so you have to adjust the volume on the Monitor/TV/AV Amp ..etc

still cannot get HDMI audio output.

cloverHDMI method/HDMI audio is working with attached IOReg (Post #14).
Nvidia HDMI audio codec not recognized, see AppleHDA HDMI Audio/Post #2
