I wonder if that is related to the built in HDMI audio ? Do you have that selected in your bios ? There is a switch for it.

 

[WonkeyDonkey]

Did you use an old DSDT or create and patch a new one ?

 

[WonkeyDonkey]

A new one correctly patched is the best bet for sure.

 

[WonkeyDonkey]

Are you using iGPU ?

 

[WonkeyDonkey]

Have you tried to patch the DSDT from your current setup ?

 

[WonkeyDonkey]

Yeah of course. What does the bios say for HDMI audio ?

 

[WonkeyDonkey]

A quick check of the USB settings in the DSDT proves it isnt patched. Its had the errors removed so it compiles cleanly, but had no patches applied.

 

[WonkeyDonkey]

No, no, no.

There is a specific set of patches that have been matched to this board. If you start randomly applying generic patches you wont get the desired end result, and will probably make things worse.

All the required patches are in the Z87E-ITX thread that we all posted on when OSX changed the internal USB settings. They are the most up to date patches and the ones you will need.

Do you know how to get a clean untouched DSDT, you should do that first.

At the Clover boot screen, press F4. A copy should be saved in your EFI folder.

Dont touch the file. Attach it here.
