Ivy Bridge + discrete HDMI audio

[fozzylyon]

I've searched for working examples of ivy bridge + discrete hdmi audio, but haven't found anything.

To anyone that has an ivy bridge system with hdmi audio + video from a discrete graphics card, I'd like to know what build has worked for you.

Thanks in advance!

For Ivy Bridge discrete graphics HDMI audio, use the Lion Guides. Everything is the same. Start here Lion HDMI Audio - Part 2a: DSDT Edits/Discrete - AMD/Nvidia

My current build (3770k + ga-z77-ds3h + 570 Ti) doesn't seem to support it. So, I'm hoping that someone's had success with either a different mobo, different gpu, or both.

Does a 3770K/p8z77i deluxe/gtx 570 hd system with HDMI audio qualify? OS X HDMI audio will not work on your or any z77-ds3h system until you do the dsdt edits.

Toleda,
What about the new UEFI BIOS for my MoBo? When I install this, then no DSDT will be required anymore. Does that mean, I have to follow your guide for encoded DD / DTS (which is working now), but without the DSDT part?

Thank you

Even with UEFI, you still have a dsdt. The functionality provided by the native dsdt may satisfy your needs. HDMI audio is not available in the native dsdt. With or without UEFI, a HDMI audio edited dsdt is required for HDMI audio in OS X.

Thanks

If I would extract the vanilla "UEFI" DSDT after the BIOS Update, would the required DSDT-edits for HDMI-sound be the same as described in your guide?

Yes.

Yes.

OK, thank you!

I am running out of ideas with my attempts to get HDMI audio working with my new GA-Z77X-UP5 TH with an Zotac GTX680.
It seems as if this UEFI bios is a bit different from my old GA-H61N-UBSB3. So the guide didn't work for my new system right now.

I already built a DSDT working and having no errors or warnings. It already has a PEGP, but simply replacing it with the generic patch doesn't work.
Even a replacement of the Device(PEGP) with the generic code leads to an error due to an already existing _PWR in a Scope (?) definition.

@Toleda: I attached my IOReg and the "vanilla" DSDT.dsl for this configuration. It would be nice if you could have a look on it.

I think this wonderful new board in combination with a discrete Nvidia graphics card will be a popular combination for new builders.
Perhaps you could help a lot of others too.

Thanks in advance,

Yicker
