Hi - This is my first build and I too am struggling with getting audio output through HDMI. My monitor is a Sony TV, model KDL 32EX500 running at 1080p.
My setup is a CustoMac from the October buyer's guide running OSX 10.9 Mavericks (MultiBeast 6.0.1):
GA-Z87MX-D3H, BIOS F3
i7-4770
SanDisk Extreme SSD
IOGear Bluetooth GU521 dongle
TP-Link Wifi card
Vantec PCIe Firewire Card (uses TI chipset)
No graphics card and running graphics via inbuilt HD4600
In MultiBeast I built the boot with DSDT-free, ALC-892 DSDT-free selected, etc.
I have tried following the guide for both the DSDT and SSDT approach but with no luck. After the DSDT I did a fresh install of Mavericks and the performed the following:
1. Removed HDAEnabler1.kext from S/L/E
2. Confirmed no property injection in
Extra/org.chameleon.Boot.plist
3. Checked version of AppleHDA.kext and patched per instructions
4. Checked version of AppleIntelFramebufferAzul.kext and patched per instructions
5. Rebuilt kernel cache using DPCIManager_ML
6. Confirmed no pre-existing Extra/SSDT.aml file
7. Downloaded
https://github.com/toleda/audio_hdm.../audio_ssdt-hdmi-ami_hd5k-amd-nvidia-1_v1.zip, extracted, renamed and added to Extra/SSDT.aml
8. Made copies of SSDT.aml renamed SSDT-1 through SSDT-5 and added to Extra/ folder. (I gathered that this was what was required per the instructions but also tried using a single SSDT.aml, also didn't work)
9. Rebuilt kernel cache using DPCIManager_ML
10. Restarted and checked IOReg values as per trouble shooting section. I also checked Preferences/Sound and no HDMI option for output.

Any help greatly appreciated as I'm at a total loss. Thank you.
