Hi Toleda,

Don't understand why AMD/Nvidia not found. I checked About this Mac/System Report/GraphicsDisplays, it does show that Nvidia is present:

Hi,

After surfing the web, since installed sierra on my hp 4530s, still can't figure out how to make HDMI audio working,
I'm using voodooHDA , i have headphones and mic working, sound preferences showing Digital out put, but no audio.

Anyone ?

Thanks in advance.

ps. on voodoohda controls, i can se digital hdmi pointing to the same address as headphones, some like AppleACPIplataformexpert/PCI0 ... i think problem relies on that.

Just a lazy question:

Is HDMI audio with AMD cards Framebuffer related? (Remember i used "audio_cloverHDMI_120_v1.0command" successfully)
Got a HD6750, which uses AMD6000Controller with patched Framebuffer and got working HDMI audio output.
Got a RX460, which uses AMD95000Controller with patched Framebuffer and got NO working HDMI audio output (detected but just silence).

But both HDAU entries within IORegistryExplorer shows correct values:
entries for HD6750:

entries for RX460:

Systeminformation:

As you can see, all HDMI audio connectors identified successfully, but only HDMI from HD6750 gives a sound.
RX460's HDMI stays silent.

Attached: my SSDT and IORegExplorer
Info: HD6750 sits in PCIe-Slot#0, RX460 sits in PCIe-Slot#4

HDMI audio is configured correctly, AMD9500Controller problem
AMD8000Controller has never made HDMI audio.
