OpenCore stuck on bridges 3 : devices 14

[Feartech]

I'm trying to get my external speakers to work...

what have you tried since? also uploading your zipped OC folder may help

Frustrating this, isn't it?

The process is as follows:

1) Discover your audio codec. If it isn't listed in your PC specs then run Windows and check the Device manager to find it.

2) With that to hand check the AppleALC Wiki/FAQ to see if it is supported, and what the possible layout-IDs could be.

3) Install AppleALC.kext (along with Lilu.kext), declare in config.plist and add the first ID either to a DeviceProperties entry OR an alcid= boot-command in the NVRAM section of your config.plist.

4) Reboot, reset NVRAM from the OpenCore boot menu. Boot again and test audio.

5) Repeat until you find the correct ID.

OR

a) Install VoodooHDA.kext instead. Declare in config.plist.

b) Reboot.

One of these should work. If not pack up and go for some fresh air.

Any problems with the efi?

Lilu.kext should be at the top of the list in your config.plist

may not need this section if using VoodooHDA:

<key>PciRoot(0x0)/Pci(0x1B,0x0)</key>
            <dict>
                <key>AAPL,slot-name</key>
                <string>Internal@0,27,0</string>
                <key>device_type</key>
                <string>Audio device</string>
                <key>hda-gfx</key>
                <string>onboard-1</string>
                <key>model</key>
                <string>8 Series/C220 Series Chipset High Definition Audio Controller</string>
            </dict>

surprised to see no aml files in your ACPI folder

also just seen that an issue with voodoohda on big sur:

So Catalina, and or lower version of Big Sur is best way to go?

one way to go...

or find your Audio Codec and use AppleALC which would be better choice
