SOUND PREFERENCES

MY PC SPECIFICATION:

• MODEL - OPTIPLEX 3050 MICRO
• OS - macOS Big Sur 11.4 (I think that this problem might occur on other versions too)
• BOOTLOADER - OPENCORE 0.7.1
• AUDIO CONTROLLER - Codec Audio Realtek ALC3234

WORKING:

• AUDIO TROUGH INTERNAL SPEAKER
• HEADPHONES

- MIC (Not tested but detected in audio settings)

MORE INFO IN MY GUIDE, THERE IS MY EFI FOLDER AND SOME OTHER INFORMATION

​

PROBLEM:

I did a successful installation of macOS Big Sur 11.4 and during a check i noticed that the audio didn't work. I tried to do the steps suggested by Dortania Post Installation Guide and other solution that i found on internet but nothing solved the problem.

​

SOLUTION:

After some internet surfing i found a solution in this post. I noticed that my audio section was set like this: "PciRoot(0x0)/Pci(0x1B,0x0)", and by changing it in "PciRoot(0x0)/Pci(0x1F,0x3)" i finally solved my problem.

I also set layout_id = 11 - (This value depends on the audio controller, please take a look to the Dortania guide that i mentioned before).
