Haswell HDMI Audio

None. Not sure what was attached, suggest MaciASL for dsdt editing.

Sorry it was not clear at all. It was an IOReg dump. I'm now attaching 2 ioreg dumps, one with my custom DSDT and one without. In both cases, no HDMI audio in sys prefs.

In both cases I confirmed they're loaded as SSDT-6 by extracting them with MaciASL (which is what I use for DSDT edits).

On a separate note, any idea why I can't boot while using drop ssdts? Will my PWM ssdt still work (it get's loaded as SSDT-5)?

The ssdt is working, what HDMI device is attached?
unedited dsdt has no effect, not needed.
PM ssdt is working
No idea why 9 series cannot drop tables.

I was playing dropping individual tables, unfortunately I left my results on a sticky note at home, I'll get them up soon.

IGPU is disabled, GTX 760 is set as primary. No HDMI devices are hooked up (monitor is DVI only, but I can plug it TV to test) however that shouldn't stop the interfaces from showing up in system preferences right?

Also just to clarify, I'm using vanilla AppleHDA since I don't need onboard audio (using USB).

No. No HDMI connected, no HDMI choice in Preferences.

Oh I was unaware of that, I'll test asap.

I can confirm, upon plugging in an HDMI screen 1) HDMI out shows up in system preferences 2) audio plays over HDMI device's speakers.

Hello toleda,

I have a short question. Is the space after SaSsdt correct? Thanks.

Absolutely.

Ah, ok. I was unsure, because there is no information about the space in your guide on https://github.com/toleda/audio_CloverHDMI
