Mountain Lion: MultiBeast - No Audio/Solutions and Problem Reporting

[pbouton]

My Audio only works with UseKernelCache-Yes in org.chameleon.Boot.plist

I use Multibeast 5.21 with Realtek ALC8xx without DSDT


My config :
Motherboard MSI Z77MA-G45 with SB i2500k


Any ideas ?


TIA

That is good. What are you trying to fix?

Hi Toleda,

Sorry my mistake : I want to say "My audio works only with UseKernelCache-No

1. Install 10.8.2 Combo update (ML AppleHDA.kext)
2. Make a backup of S/L/E/AppleHDA.kext
3. Install S/L/E/HDAEnabler1.kext

IOReg shows your codec. It also show the enabler is causing your audio problem. Solutions:
1. Remove the enabler and add dsdt/HDEF, see ML: How to Add or Edit dsdt/HDEF. Run MultiBeast 5.2.1 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/With DSDT/ALC888 Legacy. Even with dsdt/HDEF, 888 Legacy may not work with your 888_v100101.
2. MultiBeast/Audio/Universal/Voodoo

Edit DSDT now I can see HDMI in system report and graphics show Chipset Model

What is dsdt/HDEF/"platformFamily"? Not required, not tested. The PEGP edits are incorrect. The native P0P2 and PEGP have the same PCIe address; problem. Suggest new dsdt, rename P0P2 to PEGP. Edit new PEGP with GFX0 and HDAU. Reply with edited dsdt and IOReg.

Regarding HDMI audio, looks like the HDMI connector in the Eulemur framebuffer needs an edit for OS X HDMI audio. See Lion HDMI Audio - Part 3a: Kext Edits - AMD.

But I have no sound in headphones front.
What should I modify the AppleHDA for ALC892 audio??

The MultiBeast/ALC892 supports front headphone. Verify front panel HD Audio (not AC97) connector is plugged into the front panel audio connector on your motherboard. With something playing in iTunes, select System Preferences/Sound/Output/Internal Speakers and plug the headphones into the front panel green port. Does Internal Speakers change? Does sound switch from speakers to headphones? Reply with results, motherboard model and a copy of IOReg. [Guide] How to Make a Copy of IOReg.
