Loss of Audio after installing Clover Bootloader

[jam3l]

As a means of returning full functionality to the Messages app, i installed the Clover bootloader over Chimera. As i installed the boot loader i had audio (the installer made a sound to confirm the installation) now however, i do not have audio. I can turn the audio up and down, but regardless, i cannot hear anything. Also i am running the latest version of Mountain Lion. Any help would be appreciated, and while im at it i might as well ask if anyone has a guide up for enabling audio over hdmi for my setup. Thanks.


Here are my specs:

MoBo: GA-Z68XP-UD3
CPU: Intel Core i7 (Sandy Bridge)
SSD: Samsung 830 Series
GPU: AMD Radeon HD 6870

Attach a copy of IOReg. [Guide] How to Make a Copy of IOReg.
For HDMI audio, Mountain Lion HDMI Audio

I installed too for the iMessages hack. Work fine except hdmi audio. (Output audio optical is ok). I'm using the same DSDT which work fine with Chimera

HDMI audio is ok with Chimera and a self extracted DSDT + HDMI patch.

It's not very important, but if I can get working hdmi with clover, I will consider installing clover definitively.


Config: H77N-wifi + HD4000

IOreg in attach.

Work fine except hdmi audio.

IOReg shows the 05 frambuffer is loading and it does not have a HDMI connector. Verify the dsdt has 0A injection:

                        "AAPL,ig-platform-id", 
                        Buffer (0x04)
                        {
                             0x0A, 0x00, 0x66, 0x01
                        },

If dsdt is correct, Clover is injecting the wrong framebuffer.

Thanks for answer.

No I don't find this code in my dsdt.

Hi,

just got my GA-H77N-WIFI with i3-3225 yesterday and I'm trying to setup the system right now.
To get HDMI sound working, I tried the attached DSDT and replaced the _DSM section as mentioned. Still got no audio though :-/

What problem are you having with Clover; way off topic. Undo what you did. Repost in in Audio forum or HDMI Audio forum.
