Mountain Lion HDMI Audio

[Gerard71]

All you need for the GT 640 HDMI audio is now in your dsdt. Yes, connect the HDMI cable to the GT 640. Install the dsdt and restart.

hello Toleda I put the dsdt, turned on the TV, rebooted
it does not work, no HDMI in sound preferences


could you verified the dsdt post #180
if you have time thank you


I put the ALC898 kext from MultiBeast 5.0.2 with dsdt

Necessary but not sufficient. Check System Preferences/Sound/Output/HDMI. If no HDMI listed, HDMI audio is not working. Attach your edited dsdt and a copy of IOReg. [Guide] How to Make a Copy of IOReg.

Not enough information. I cannot answer your question until I see the IOReg. I know what the screenshot looks like when I see an IOReg; I cannot see what is in the IOReg with a screenshot. Unless I ask for a screenshot, reply with an IOReg every time you change/test something.

You are driving me nuts. This thread, Mountain Lion HDMI Audio with this edit hd4000_hdmi_audio_dsdt_editing_kit_v1 is obsolete. Delete anything you did with that method.

The only kit you should be using is HD4000_AMI_EFI_hdmi_audio_dsdt_editing_kit from this thread Mountain Lion HDMI Audio - AMI DSDT. Apply the edits to the dsdt, compile and install

You cannot use an enabler with a dsdt. You have to use a dsdt for HDMI audio . Deleted the enabler.

Reply with the edited dsdt and a new IOReg.

Hey Toleda:

Recently updated to 10.8.2 and lost audio once again by HDMI o HD3000. Here's my DSDT and IOReg file. I made no changes after update.

The update replaced S/L/E/AppleHDA.kext with the 10.8.2 native AppleHDA.kext. I'll bet you did not backup S/L/E/AppleHDA.kext before you did the update. Your choices are:
1. leave dsdt with current layout-id, run MultBeast 5.0.1/ALC whatever (add motherboard to your profile)
2. edit layout_id to 3, run Mulibeast 5.1.1/ALC whatever, see Mountain Lion: Optimized AppleHDA for Realtek ALC8xx

 

[toleda]

Much better.

Edit dsdt/HDEF/layout-id to 0x03, 0x00, 0x00, 0x00
Run MultiBeast 5.1.1 - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/With DSDT/ALC892

For more information, see Mountain Lion: Optimized AppleHDA for Realtek ALC8xx

What audio devices show in System Preferences/Sound/Outputs and Inputs?

You missed a step
Mountain Lion HDMI audio - Verify S/L/E and org.chameleon.Boot.plist
1. Delete any and all audio enablers (HDAEnabler8??), helpers (ALC8??), etc.; AppleHDA.kext only.

Delete S/L/E/HDAEnabler1.kext, repair permissions and cache and restart. Reply with new IOReg,
