The edits are the same for discrete graphics cards. What matters is the BIOS, motherboard and processor. Assuming your profile is accurate, use HD4000_AMI_EFI_hdmi_audio_dsdt_editing_kit in Mountain Lion HDMI Audio - AMI DSDT.Hello can someone please tell me which guide i should follow to enable HDMI audio on my Sapphire Radeon HD 6870?
Every Intel system has a dsdt.I had a look at the guide but i cant make any sense of it. What should i do if i have no DSDT?
