Mountain Lion HDMI Audio

[dragadog]

Hi Toleda,

I'm back again, having given up trying to get HDMI audio working the GT 210, and instead trying with the integrated HD4000 chipset.

So the good news is I got HDMI audio working (yay!). I installed the 10.8.2 update, then ran your DSDT patch file, and the HDMI output finally showed up and worked.

My issue now is I don't have any other audio outputs. Ideally I'd like to have analog and SPDIF working, but I'd settle for analog. Can you glean anything from the attached DSDT.aml (currently being used) and IOREG extract?

Thanks,

f.

Ok... I've done something wrong and I'm not sure what. I have no audio outputs. Here's my IOReg and edited DSDT.

The attached dsdt has no audio edits. The result is no audio. Make the edits as described in the guide. Attached an edited dsdt and new IOReg.

Wrong layout-id. You are using the Lion layout-id which does not work in ML. Reply with correct ML layout-id.

Hmm... that is strange. I check for them before installing. Oh well, I'll just start fresh. Better for me to keep track of. I'll update soon. Thanks!

OK, well it worked for HDMI, but like the person before me I have only HDMI. I edited the layout-id as specified in the guide to 0x03 0x00 0x00 0x00. Here's my edits.

What color and version is S/L/E/AppleHDA.kext (Finder/File/Get Info)?

White? and version 2.3.1

I thought the correct ML layout ID was 1, as I have 6 port on my onboard audio -- is that what you're asking? Confused again....

No surprise. Updating OS X always replaces AppleHDA.kext. You have the native 10.8.2 AppleHDA installed. Install the appropriated edited AppleHDA.kext from ML: Optimized Realtek AppleHDA - Preview/Alpha.

What do you see in IOReg/HDEF/layout-id?
