IOReg??

MEI is loading, Azul is not. No other suggestions.
AirPlay Mirroring is not available when IGPU is not primary display in 10.11.

According to ioreg, you're not injecting AAPL,ig-platform-id.

No expectation of Azul framebuffer loading without it.

Separate experiment, remove Clover/ig-platform-id, install ssdt_hdmi-hd4600+_AirPlay.zip

That was ioreg from after removing ig-platform-id as requested.

Is that the final verdict? No way to get discrete graphics to work properly while setting IGPU as primary?

Why does AirParrot work so good?

You can inject ig-platform-id with config.plist. (config.plist/Graphics/Inject/Intel=true).

As toleda already stated, IGPU must be primary, contrary to the title of this thread.

So then, my next question..

Is there any way to fix the sluggish FPS of Airplay Mirroring when setting IGPU as primary display?

1. Airplay shows off all the time. .
2. 10.11.3/GA-Z87X-UD5H/F9/4770K/MSI GTX 660
3. Clover
4. IOREG Attached
5. Clover
1. config.plist Attached
2.Boot log attached.
3.DSDT Im using but didn’t change anything
4.SSDT Im using but didn’t change anything
6. Attached Graphics settings jpeg from About This Mac.

Note: When I use this ig-platform-id (04120004) nothing happened. I used this (0D220003) and Airplay options came to System Preferences.

I have same problem as telepati.
Anyone found a solution yet?

There seems to be some state where the system will show an AirPlay icon, but it is unable to create a hardware accelerated (QuickSync) h264 encoding session. I assume this is what's going on when people's issue is described as AirPlay being enabled, but it's slow/low framerate etc.

I noticed this because I have a self-written application that uses the hardware encoder and it fails to create the encoding session even when the Displays control panel indicates AirPlay is available. There's also a video encoder application named 'MacX Video Converter Pro' that shows hardware encoder status and it indicated hardware encoding isn't available.

I'm going to keep working at this to see if I can figure out what's going on, but when doing your own debugging it may be worth keeping in mind that apparently the existence of the AirPlay icon may not mean the hardware encoder is working.

Edit: Ok, I've spent a bunch of time messing with stuff, here's what I've noticed/figured out.

I'm running an i7-4790k on a GA-Z97X-Gaming 3, EVGA GTX 970. There are no displays connected to the built in HD4600. Bios is set with Integrated Graphics enabled, 64M of memory and initial display is set to PCI-E slot 1. Using Clover to boot, running 10.11.4.

With no modifications the HD4600 is recognized and the system indicates that AirPlay is available. It does work, but it's basically terrible. Low framerate, high delay, can't keep up with fast motion on the screen.

Further digging into some diagnostics emitted by my application when it tries to enable the hardware encoder lead me to one thing: The underlying OSX libraries for using the hardware encoder expect to see 'IGPU' in the IORegistry. Without this they fail. I dumped my DSDT with clover and discovered there is no IGPU device defined in it.

Using one of toleda's SSDT patches he linked to someone earlier in this thread (I believe it was named something like ssdt_hdmi-hd4600+_AirPlay), I put it in the clover 'patches' directory and rebooted. H264 hardware encoder now works, AirPlay is as good as on real apple hardware.

I guess the takeaway from this is that even if you get the AirPlay icon in the menu bar, you may not have full AirPlay functionality. Check your IORegistry for the IGPU entry, if it doesn't exist patch your DSDT/SSDT.

One curious side effect of this is that previously I had to disable the IGPU in the Bios otherwise trying to play the Beats 1 channel in iTunes would hard freeze the system. Now it no longer freezes the system, it simply doesn't properly play. Acts like it loads, but no audio or album art/song info appears. I guess that's a bit of 'progress' on that issue...
