Mountain Lion HDMI Audio

[toleda]

So my question is what is the Azalia Codec and should it be set to "Auto" or "Disabled"?

Azalia is not supported in OS X. Is there a BIOS/HD Audio setting? Are we talking about the Z68A-D3H-B3 motherboard?

- hdaenabler ok

Not OK!!!
Mountain Lion HDMI audio - Verify S/L/E and org.chameleon.Boot.plist
1. Delete any and all audio enablers (HDAEnabler1, ..8??), helpers (ALC8??), etc.; AppleHDA.kext only.
Delete System/Library/Extensions/HDAEnabler1.kext, fix permissions and cache and restart.

No change. Only the DVI display is connected. A DVI2HDMI adapter works.

I have found a kext and dsdt edit the says it will make the onboard vt2021 work with apple HDA.

When replace the Device (HDEF) section with the one on the site and I get compile errors.

The dsdt edit is wrong. See ML: How to Add or Edit dsdt/HDEF, layout-id must be edited: from 0x01, 0x00, 0x00, 0x00 to 0x0C, 0x00, 0x00, 0x00

Yes we are talking about that Mobo. If I disable it my HDMI audio still works in Windows 7. Should AppleHDA HDMI audio work if Azalia is disabled? I've played with it but unsuccessfully. I'll try it again and send you my IOREG's and console Logs.

My bad,

Still bad. IOReg says there is an enabler installed. Find it and remove it. If you cannot find it, fresh install. No response when no IOReg attached.

attached thanks!

ok?

Windows is not relevant. Azalia is obsolete replace by Intel High Definition Audio. AppleHDA.kext does not work unless it sees the codec.
