AMD Radeon HD 6570


Video seems to work fine, just audio that is not working.  No device shows up under Audio, no HDMI audio neither.

 

Here are the components

10EC:8168 Ethernet

10EC:0889 Audio
1002:AA01 Hdmi Audio
8086:27C0 Sata Controller
1002:6759 GPU

Inject via clover, devices tab, audio, put 7 there ;)

 

I am installing the aDummyHDA.kext.  I need to patch my DSDT with this codes.

#   Inject Audio info
into method label _DSM parent_label HDEF remove_entry;
into device label HDEF insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "AAPL,slot-name", Buffer() { "Built in" },\n
        "layout-id", Buffer() { 0x07, 0x00, 0x00, 0x00 },\n
        "device_type", Buffer() { "Audio Controller" },\n
        "built-in", Buffer() { 0x00 },\n
        "PinConfigurations", Buffer() { },\n
        "hda-gfx", Buffer() { "onboard-1" }\n
    })\n
}\n
