Haswell HDMI Audio

[Azimuth1]

Attach the "clean DSDT".

I've remade all the system from the ground up ... here it is.

PS: It's not manually edited at all and, at the moment, I got 3 errors so I was unable to successfully compile it...

PS: further investigation: if I load the so called "system DSDT" in MACIasl, patch and compile it, I got 3 errors, while if I save the "system DSDT" in a "clean dsdt.dsl" file (as I did to give you the file of this post), move it on a different machine and then I patch and compile it with MACIasl on this other machine I got only warning and I'm able to complete the compiling process. Weird, uh?

Did not get the file requested. Starting over means all previous information is no longer relevant.
Attach:
1. native dsdt (not "clean")
2. HDMI audio edited dsdt (clean)
3. IOReg dsdt (item 2) installed.

Hi Toleda!

I would like to understand what your perl script actually does, specifically the audio_nuc_hdmi-hd5k-azul-90_patch.

I see the command:
sudo perl -pi -e 's|\x99\x14\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x05\x12\x00\x00\x04\x00\x00\x87\x00\x00\x00\x02\x04\x14\x00\x00\x04\x00\x00\x87\x00\x00\x00\x03\x06\x10\x00\x00\x04\x00\x00\x11\x00\x00\x00\xFF\x00\x01\x00\x01\x00\x00\x00\x40\x00\x00\x00|\x99\x14\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x05\x12\x00\x00\x08\x00\x00\x06\x00\x00\x00\x02\x04\x14\x00\x00\x04\x00\x00\x87\x00\x00\x00\x03\x06\x10\x00\x00\x04\x00\x00\x11\x00\x00\x00\xFF\x00\x01\x00\x01\x00\x00\x00\x40\x00\x00\x00|g' /System/Library/Extensions/AppleIntelFramebufferAzul.kext/Contents/MacOS/AppleIntelFramebufferAzul

It's obviously doing a search/replace on the binary. Now, what I don't know is how to interpret the \x in all the command. Could you help me?

Thanks!!

How did you solve? I guess more than someone can benefit from your experience

Toleda, what are these edited codes based on? I mean, do they fit for any board? What's the thinking behind this framebuffer re-mapping?

The one Azul framebuffer for desktop (iMac14,1) does not have HDMI connectors. DP connectors do not make HDMI audio. The fix: edit DP connector(s) to HDMI connector(s) for HDMI audio.

TOleda, this is a bit of OT ... Is there any method to have AirPlay mirroring working with the HD4600 series ? thanks!
