[AudioDxe] Open PCI I/O protocol - Access Denied

[seffs]

AudioDxe is unable to connect to the audio device. Here the relevant parts in the debugging log:

When running pci in OpenShell PciRoot(0x0)/Pci(0x1F,0x3) gets reported as Mixed mode device. I've already verified that PCI address and codec are correct with ioreg. This is what I've tried so far:

• Activate DisconnectHda
• --force-device= argument in AudioDxe
• --gpio-setup argument in AudioDxe

*** Removed PlatformInfo from EFI.zip

Additional info for better context:

• Acer E5
• Realtek ALC255 (Maybe not relevant for AudioDxe, but I had some trouble finding the appropiate layout-id. It needs ComboJack fix for headset mic to work)
• This machine is kind of special regarding UEFI boot. A manual entry has to be done for OC in the FW for it to be detected. Secure Boot is deactivated already. Some security check may prevent the bootloader of connecting to the device, but given that everything else works, this might not be the case.

At first look glance, it looks to me like you have tried the right things, and it is surprising that the result is 'Access Denied'.

If anyone else looking at this can spot what the issue is, please do say so - but for now it looks to me like you've got a genuine new issue on your hardware. Please be aware the AudioDxe development may not be highest priority at the moment (especially e.g. without equivalent hardware on which to reproduce the bug). All the same, if the issue is valid, as it looks, it can be tracked here and addressed in due course, or when more info becomes available.

Noted. I added some observations too. Thanks for the effort

@seffs - Could you try the macOS XCODE5 Artifacts from this build https://github.com/acidanthera/OpenCorePkg/actions/runs/7405598402 to see if it helps?

(You need to be logged in to GitHub and you need to wait for a moment before the build artifacts appear.)

[mikebeaton]

Tested and the suggested change, now on master as https://github.com/acidanthera/OpenCorePkg/commit/b24d13e6ab6c5d3f0f8dd59f12164079fbcd0600, fixes this. Apologies for the delay in fixing this... Btw, you are correct that these Acer's are very quirky in terms of how you have to enable boot entries. ;)

Hello there, Im just starting my hackintosh build and encounter the error, I see that there's a fix on the comment above but I don't know what am I supposed to change, could you please give a short instruction according what needs to be changed please.

here's my configuration

ASUS ROG STRIX G15 G513QM macOS Ventura 13.6.3 AMD Ryzen 9 5900HX AMD Radeon Vega 8 (working) I cannot really configure what's the audio I am using

here's the last log of the OpenCore

@nelthera Just updated opencore to new built mention above. It fixed HDA: Open PCI I/O protocol (try DisconnectHda quirk?) - Access Denied for me on HP laptop.

@mikebeaton I just tested it on my E5.

It works! Thanks a lot
