VoodooHDA prefpane extension error

Hello! I successfully updated to macOS Big Sur today from Mojave via System Preferences. Since my audio codec is unsupported, I used VoodooHDA instead back on Mojave with the prefpane extension.

Now, on Big Sur, when I try loading the prefpane extension for the actual kext to work, this comes up:

Preferences Error: Could not load VoodooHDA preference pane.
