Actually I have audio problem too, the speaker works fine but not the headphone jack.

I know it's crazy but I'm not using DSDT/SSDT patches and not exactly following the guide in post #1, but it works, except for the headphone jack and the SD card reader.

You should not expect working audio without patched AppleHDA components installed and correct ACPI patches.

Guys, finally solve the HDMI/DP output issue on XPS 13 9350, credit myself,...LOL

Here's the proof


I will later update what I do to power it up. Correct the framebuffer is not enough, we have to touch the AppleHDA.

Cheers,

Getting this when awaking the computer from sleep:

It only happens when using custom HiDPI settings, when using normal resolution, there won't be this problem.

Any idea why?

What is DVMT-prealloc set to?

What is DVMT-prealloc set to?

Seems to be 64MB:

However, there is nothing in UEFI setting(or BIOS) to change that.

64MB is usually adequate for Skylake.

Actually I haven't done any changes since last time, so I'll just use last time's files.

Must re-capture ACPI/origin with F4 at Clover.
No files attached anyway.
