Audio - HDMI Audio AppleHDA [Guide]

[toleda]

So if my audio on my Motherboard doesnt work, Nvidia's wont work either.

Assuming you mean motherboard ALC audio, no. The installation of a discrete graphics card has no effect on onboard audio. To fix onboard audio, see No Audio Devices - Realtek ALC AppleHDA.

Nvidia HDMI audio, when enabled, works with or without motherboard audio. See Post #1.

Should I bother fixing the realtek - No Audio device problem? Or just go ahead with the Nvidia Graphics card audio guide?

Also

"Discrete Graphics (in addition to appropriate motherboard guide above)"

I need to follow the guide for my IGPU 4600 and the Nvidia Guide?

Hey Toleda, since your the expert and all...

Do you think my problems could be caused by not updating to the latest bios? I am on F4 and there is F8.

Should i update or not?

No.

onboard audio OFF (bios)

Why?

 

[Petko166]

Good question. Because I do not need it as I would like HDMI audio.

I know it is a different story but Windows works with HDMI audio as onboard audio if off.

Hello again,


Earlier I mentioned that your suggestions made things work for HDMI audio and again I thank you. So I am closer to getting the audio completely working. However, audio over DisplayPort is not working yet.


As per your suggestions in your earlier reply:


1.) I ran the script ./AppleHDA8Series.sh -b AppleHDA -b AppleHDAController which gave me a new AppleHDA1150.kext


2.) I ran the script graphics_intel_hd5k-azul-c-90_patch.command from the guide http://www.tonymacx86.com/graphics/125239-hd4600-hd4000-hd3000-framebuffer-edits.html
The c version was chosen because it was the closest match to my configuration: DVI at port 0x5, HDMI at port 0x6, and DP at port 0x0.


And I did get audio over HDMI.


However, there is no audio source available for the DisplayPort option. I tried two different DP cables with the same result.

The HDMI option only appears in the sound preferences when a HDMI connection is actually there.



I have enclosed a new IORegistry Explorer report and new DCPI and System Audio screen shots. No other changes have been made to the system.
