Audio - HDMI Audio AppleHDA [Guide]

[toleda]

My current "testing" boot.plist is

###
    <key>HDEFLayoutID</key>
    <string>79030000</string>
    <key>EnableHDMIAudio</key>
    <string>Yes</string>
    <key>Vendor10deDevice06dd</key>
    <key>DSDT</key>
    <string>/Extra/DSDT_2014.aml</string>
<key>HDAEnabler</key>
<string>Yes</string>
<key>HDEFLayoutID</key>
<string>01000000</string>
    <key>SMBIOS</key>
    <string>/Extra/smbios.plist</string>

Problem: dsdt/HDAU injection appears in IOReg/GFX0.
Test boot.plist has unfamiliar flags and duplicate settings. Remove all flags noted above except DSDT key and string. The dsdt injects the required audio flags.
Install MultiBeast 7/ALC889
Reply with new boot.plist and IOReg.

I have HDMI audio but stereo comes out mono and DTS/Dolby Digital are coming out of wrong speakers. My Amp always says PCM.

Configuration is correct.
What DD/DTS sources, player, receiver, etc.?

The sources are Plex and VLC .mkv files with DD/DTS audio tracks. Is there some additional settings to configure the speakers?

Is there some additional settings to configure the speakers?

OS X does not touch the audio stream; passed directly from the graphics card HDMI audio codec to the receiver for decoding. Any speaker problem is receiver related.

Nvidia GeForce 210

AppleHDA.kext does not support GT 210 HDMI audio.

I really don;t like this version of AppleHDA though, audio's gone after waking from sleep.

IOREG included, I can only see one HDAU entry but for some reason DPCIManager reports I have 4 gtx470 devices 0x10de0be5, and in the pci list I can clearly see that the quadro is 0x10de06dd

Extra step needed for the quadro?

EDIT : found this for the no audio after sleep. Testing it, looks good so far https://github.com/cliffom/appleHDAReset/releases?

One HDAU supports all 4 Nvidia HDMI audio codecs.
The problem noted previously is still present. It is an ACPI table problem, not a kext problem.
What bootloader? Attach DPCIManager/Misc/Boot Log.
To solve the HDMI audio problem, it is important to minimize what is different from the norm. If solved, you can experiment with any AppleHDA.kext.

I was not aware of this boot log in dpcimanager! Pretty cool actually!

Here it is!
