Haswell HDMI Audio

[toleda]

Is there any method to have AirPlay mirroring working with the HD4600 series?

AirPlay Mirroring works natively. Requires enabled HD4600 graphics, APM sysdef and AppleTV.

See Post #1, AppleIntelFramebufferAzul.kext/Framebuffer 0x0300220D/edit
Changes 2 DP connectors to HDMI.

Got it! So, if I'm not wrong, we are changing connector #1 to HDMI, connector #2 stays DP and connector #3 is still unknown.

No.
0105: DP > DP (no change)
0204: DP > HDMI
0306: DP > HDMI

Toleda...can you look at this IOJones file I put up a few days ago?

 

[toleda]

I patched Azul according to post #25 and it still doesn't work.

The edit is not installed. Try again. Must rebuild cache before restarting.

Let me try to understand this before getting myself confused lol:

1. I have to edit the AppleIntelFramebufferAzul.kext according to post #25 with HexEdit
2. Install the kext with DPCIManager
3. Then rebuild the cache in DPCIManager

How long does it take to rebuild the cache?

Yes, less than a minute.

Yes, less than a minute.

This is getting strange now...

I extracted the AppleIntelFramebufferAzul.kext from S/L/E and placed it on my desktop. Opened up HexEdit and made the following changes like you've stated from post #25, not post #1 (I noticed they are two different changes). Save the new file on my desktop, then placed that file in S/L/E Azul.kext/Contents/MacOS folder. After that, opened up DPCIManager to install the kext file. I let the cache rebuild (left the computer alone for about 5 minutes just in case) and then restated the computer. Still no option to change the audio, also I don't see AppleIntelFramebufferAzul.kext in S/L/E anymore. Attaching my IOJones file.

HexEdit the Azul file on your desktop and HexEdit/Save. HexEdit installs the edited binary in the kext. No need to touch it. After the edit you see the edited binary and a backup of the original binary. Have DPCIManager Install Kext/Repair Permissions/Rebuild Cache. The last message of the cache rebuild is no supported helper partitions to update (2 times).

No IOJones.
