Mavericks and HDMI sound on Radeon HD 6450 1GB DDR3

Hi Folks,
I have everything running on 10.9 except HDMI sound. Thought you might be able to help me out get HDMI Sound out of my graphics card (Sapphire Radeon HD 6450 1GB DDR3). I get video no problem but no sound. Let me know if I can do anything. Really appreciate it if you could help. Thanks.

You get to do everything, see Mavericks: HDMI Audio - AppleHDA

Hi toleda,
Will the following method work ?
Download

audio_ssdt-uefi_hdmi_v3.zip

Installation

Copy Downloads/ssdt-audio_uefi_hdmi_v3/SSDT-1.aml to Extra
If Extra/SSDT.aml is present, install Downloads/audio_ssdt-uefi_hdmi_v3/SSDT-1.aml as Extra/SSDT-1.aml
If no Extra/SSDT.aml, rename Downloads/audio_ssdt-uefi_hdmi_v3/SSDT-1.aml to SSDT.aml and install as Extra/SSDT.aml
The 1st SSDT is SSDT, 2nd is SSDT-1, 3rd is SSDT-2, etc.; no gaps

Enable SSDT
Chimera or Chameleon - Extra/org.chameleon.Boot.plist
Code:
<key>DropSSDT</key>
<string>Yes</string>

Clover_v2000+ - EFI/CLOVER/config.plist/ACPI/SSDT
Code:
<key>DropOem</key>
<true/>

Rebuild kernel cache - see Tools: 4
Restart
Verify HDMI audio

Will the following method work ?

What version is the installed BIOS? What booter?

You don't have UEFI, see HD3000/6 Series MB HDMI Audio (dsdt or ssdt) - Desktop

Hi Toleda,
Will my ML audio edit dsdt work on Mavericks. See below:
ML_DSDT-HDMI_Audio_Edits_v4.1

No, those edits are for experts.
Mountain Lion HDMI Audio - Award DSDT - tonymacx86.com, use HD3000/6 Series MB dsdt edits - Desktop

Configure MaciASL/Preferences/Sources/+ with URL:
Code:https://raw.github.com/toleda/audio_hdmi_hd3000/master

I added the above URL in the MaciASL. Now where is the "apply"button? And what do i do next?
