Hide USB Audio device on MAC OS X using custom kext
https://stackoverflow.com/questions/15942765/hide-usb-audio-device-on-mac-os-x-using-custom-kext
1 The recommended way to do pre-processing of a USB audio device's input and output streams in kernel space is to use the AppleUSBAudioPlugin API. This kext does not appear in the list of devices because it isn't an instance of IOAudioEngine, so there is no "hiding" involved. Share answered Jan 9 '15 at 18:28 Draxillion 568 3 6 Add a comment

With the New Lilu.kext and macOS Catalina, if there’s no Audio detected, remove the codeccommander.kext, it may solve the problem.

https://github.com/RehabMan/OS-X-USB-Inject-All
This kext attempts to inject all ports for each controller, and for hubs as well. You can use this kext (temporarily) to enable all ports so you can determine which ports really need to be in the final injector. Only the (potential) hub on EH01.PRT1 and EH02.PRT1 are injected. Other hubs would require modifications.

https://developer.apple.com/forums/thread/133318
Hello, DriverKit does not have an audio specific framework. The DriverKit documentation lists the following frameworks: 'USBDriverKit', 'HIDDriverKit', 'NetworkingDriverKit', 'PCIDriverKit', 'SerialDriverKit', and 'USBSerialDriverKit'. If this is a 100% USB Audio class compliant device then it should be natively supported by macOS, and a dext (or kext) should not be required.
