Mountain Lion HDMI Audio

[toleda]

The HDMI Audio works but the onboard has disappeared.

What AppleHDA.kext are you using for your VIA codec? What layout-id?

hi toleda,

GTX650Ti EVGA - 2 DVI outputs, 1 mini HDMI- which of these can have HDMI audio on H67N-USB3-B3? (Obviously, not all simultaneously) All 3 outputs on the GTX650Ti?

thank you,

jwk

success with Geforce GT620-2GB EVGA!
HDMi working perfectly as you can see in the screenshot.
So it was necessary to edit DSDT.aml.

Yes, with DVI2HDMI adapter. Current dsdt edit supports 2 HDMI audio outputs. Add the following code to Device GFX0 and change Store (Package (0x06) to (0x08):

                                "@2,connector-type", 
                                Buffer (0x04)
                                {
                                    0x00, 0x08, 0x00, 0x00
                                },

Always. Enjoy.

Toleda should make a database with the plates graficas
that users were successful with HDMI audio.
what do you think?

                                {
                                    0x00, 0x08, 0x00, 0x00
                                },

Wow, am I dreaming??? I plugged AV receiver into one of the DVI ports using DVI-to-HDMI adapter prior to doing any edits, and found that AV receiver was listed in the 'Sound' 'Output' Preferences... tried it with Sound Effects and it works! Checked the other DVI and the Mini HDMI ports and HDMI audio is working there too! Native HDMI audio in ML! This is too good to be true- am I missing something??? Using Nvidia Release 304.00.05f02 in ML 10.8.2...

I have success!This KEXT http://www.osx86.net/downloads.php?do=file&id=3041

And this added into the DSDT:

"layout-id",
Buffer (0x04)
{
0x0c, 0x00, 0x00, 0x00 
}, 

"PinConfigurations", 
Buffer (0x30) 
{
0x10, 0x40, 0x11, 0x01, 0xF0, 0x00, 0x00, 0x40, 
0xF0, 0x00, 0x00, 0x40, 0xF0, 0x00, 0x00, 0x40, 
0xF0, 0x00, 0x00, 0x40, 0xF0, 0x00, 0x00, 0x40, 
0x50, 0x30, 0x81, 0x01, 0x60, 0x90, 0xA1, 0x90, 
0xF0, 0x00, 0x00, 0x40, 0x20, 0x21, 0x45, 0x07, 
0xF0, 0x00, 0x00, 0x40, 0xF0, 0x00, 0x00, 0x40
}

Only things missing are my front headphone port, but the header isn't connected yet so that may explain it, and I cant seem to get AC3 passthrough on the HDMI? maybe that AppleHDA KEXT is broken there.
