[nosipy8]

Hi, I'm trying to get hdmi audio through my nvidia 570 but i get nothing. I'm on ML and I try also to get audio throgh my motherboard, which is a GA EP43T-USB3, and the result is the same. No audio at all. So if anybody has the same graphic card o motherboard and has been able to enable the audio please tell me. Im very noobie in mac so please forgive me about that. Thanks in advance

Extract your dsdt, see [GUIDE] Creating your own DSDT for most boards
Onboard audio, see ML: How to Add or Edit dsdt/HDEF, use Audio ID: 1.
HDMI audio, see Mountain Lion HDMI Audio - Award DSDT, use ML_5-Series_Award_hdmi_audio_dsdt_editing_kit.

I stuck in the step 2. I got my dsdt.aml, which I think is ok although I'm going to attach here. When I want to complete de second step I don't know how to carry on I followed the guide, I downloaded the ML_HDEF_AUDIO_IDS_1 and from there I dont know how to going on. You said that is supposed to change the hdef_audio_id1 layout to my, which is a Realtek 888. But I get nothing. Any walkthrough please?
Again, sorry for that and very very thanks toleda.
I attach my dsdt file, which I think is ok.
