I spent a bit of time reading the instructions for this method and I'm not sure it will work for me.

The most suitable patch says it will only work with AMI bios and my bios is ACER

Also it says to remove HDAEnabler1 (is this the same as HDAEnabler?) and any injection both of which I need to enable sound and graphics.

What would I have to do to manually edit my DSDT for this?

Hi Toleda!

 

Your tutorial, works in chip series 76?

Screen Shot 2014-02-12 at 8.46.45 AM.png

 

Or only this is supported?

Intel Motherboards

8 Series - Z87, H87, B85

7 Series - Z77, H77, B75

6 Series - Z68, P67, H67, H61

5 Series - P55, H55

 

 

Thanks

Why no sound In a yellow box 

System Information/Hardware/Audio/Intel High Definition Audio (not Devices), what is your Audio ID?

The orange port is the 2nd Line Out in System Preferences/Sound/Output.

For screenshots of what does what, see (View Raw), audio_ALCInjection/M-Realtek_ALC_AppleHDA_Screenshots.pdf.zip at master · toleda/audio_ALCInjection

Your tutorial, works in chip series 76?

Thanks, here are all the files I think you might need.

Missed your post.  Several issues.

What version is AppleHDA?  There will be problems if it is not v2.5.2 or newer.

Remove the audio enabler.  Confirm onboard audio is working,  Back up the dsdt

dsdt is AMI, has dual link injection and does not have GFX0/hda-gfx injection

Compile, delete line with error, compile

Edit dsdt, compile, save, install.

Since the IOreg does not have an HDMI device attached, no way to know what framebuffer edits are required.  

Reply with edited dsdt and new IOReg withedits and HDMI device attached.

Find "AAPL00,DualLink", add additional injection as shown.            

Method (DSM, 4, NotSerialized)
            {
                Store (Package (0x08)

Thanks for the reply,

First off my onboard audio alc269 will not work without HDAEnabler :(

I also have no idea what version hda I'm using.

When I first installed Mavericks I trawled the web for an hda that worked, the only one I found didn't have working mic.

Mirone kindly patched it so that mic now works.

Is it just a case of applying whatever patches have been made to my hda to a newer hda or am I going to need an edit to my dsdt?

I think I need to concentrate on getting audio working without HDAEnabler first.

Enabler and dsdt/HDEF/layout-id do the exactly the same thing.  What ever IOReg/HDEF/layout-d is working with the enabler will work with the dsdt, edit layout-id to same.  Regarding AppleHDA.kext version, use Finder/Get Info.

Thanks, my HDA is an old version so I'm working on patching the latest had.

With regards to eliminating the need for HDAEnabler I have found the following info from my DSDT and ioreg.

 

DSDT

Under HDEF

"Layout-id"
Buffer (0x04)
{
    0x1c, 0x00, 0x00, 0x00
}

OIREG

HDEF@1B
Layout-id         Data         0D  01  00  00 

Is it as simple as changing 

 

0x1c, 0x00, 0x00, 0x00

to

0x0d, 0x01, 0x00, 0x00

hrm. My current hack is listed in my signature, and all I seem to need to get operating now is the hdmi audio; will this method work on motherboards using amd chipsets?

I have no experience with AMD chipsets.  I believe a few users have HDMI audio working on their AMD systems.  Suggest posting in the AMD forum.
