Hi,
I'm blocked trying to get HDMI Audio working after doing a clean install of Sierra. I'd love any help anyone can offer.
Description of HDMI audio problem
Upgraded from Mavericks /Chameleon to Sierra/Clover and the HDMI sound no longer works
OS X version/motherboard model/BIOS version/processor/graphics
- Gigabyte GA-Z77-WIFI (LGA 1155)
- Intel Core i7-3770
- 240GB SSD Drive
- No graphics card
- Samsung 43” Plasma TV Monitor F4500
Procedure/Guide Used
1. Flashed bios and updated to F3. Updated settings to the recommended settings (changed VT-d, and XHCI Handoff, didn’t see CFG-Lock, or OS Type, or IO Serial port)
2. Erased SSD drive and installed Sierra using Unibeast UEFI mode
Installation went smoothly and I was able to boot into Sierra
3. Ran MultiBeast, and selected UEFI Boot Mode and the following:
- ALC892
- Optional HD 3000 / HD 4000 / HD 530 HDMI Audio
Made no other alterations
4. Rebooted into Sierra and check sound settings, which now had the following:
- Line Out
- Digital Out
- Internal Speakers
But no HDMI audio. (Regular headphones and Bluetooth headphones worked fine.)
5. Next, I tried using the audio_cloverHDMI-120.command in conjunction with the EFI Mounter. Attached is a screenshot of the results. It ran with the following errors.
Print: Entry, "Comment", Does Not Exist
Set: Entry, ":Comment", Does Not Exist
Merge: Can't Add array Entries to dict
HDMI audio edited /Volumes/EFI/EFI/CLOVER/config.plist installed
Where I stand now:
When I reboot, I can’t see any changes in system controls.
When I mount the EFI partition, I see two files:
EFI/Clover/ACPI/patched/SSDT-HDEF-2.aml
EFI/Clover/ACPI/patched/SSDT-HDMI-HD4000.aml
When I view the config.plist file, I see the following changes:
Audio: 3
UseIntelHDMI (x) checked
Attached are what I hope are the necessary files to solve the issue.
Thanks again.
