Elitebook 8470p / HD4000 Fixing DP kills Audio

[dreadkopp]

Hey guys.

 

So far I got everything to work on this little machine. Except the Displayport. I never had a Intel IGP before so I am a bit lost. I will attach my Clover folder, would be great if someone could have a look.

 

I used mostly patches found here: https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patchsince I couldn't get the IGP to work properly at all without it. (inject intel + platform id 0x01660009 / 0x0166000A just gave me 4MB Vram and graphical glitches)

 

config : CLOVER.zip

 

Thanks in advance

Use 0x01660003 as your ig-platform-id to get video running with 1536 MB VRAM.

Then use the following KextsToPatch-Entries:

Dankeschön @al6042

 

UPDATE:

 

by setting the 0x01660003 platform-id in the SSDT-IGPU_HIRES.aml and stripping the kext patches by the first one (HD4000 Scramble) it works...

 

Using the first Kext Patch i will get a KP + Reboot.

 

However sound device is gone now. I was getting sound to work with lilu + applealc + layout 12.

 

I can reproduce this by en-/disabling the kext patch for lvds connector.

 

so i can have: sound but no internal display

 

OR no sound and DP Display + internal Display working.

 

 

Weird, i know. but if anyone has a solution to this please help Currently using Voodoohda but sound is bad ... :/

In that case you might should take a look at my old DSDT, which I used, when I had the laptop myself...

 

It contains the HDEF-Patch for the "IDT 92HD81B1X" with layout-ID 12...

Hey Al

 

 

 

Frohen ersten Advent!

 

 

 

i used your DSDT while dumping all of my ssdts besides the cpu-powermanagement as well as all clover-on-the-fly dsdt patches, set 0x01660004 platform id manually in clover + inject intel.

 

However i end up with the exact same result:

 

using the kextpatch for lvds disables audio, disabling the kext patch gives me audio but i loose internal monitor.

Too bad...

I don't have the laptop anymore to be of more help... Sorry

[dreadkopp]

Fixed it. It was Clovers fault. Used 4259. Update to 4330 fixed the sound problem.

 

Now pretty much everything works, still waiting for Wificard though.
