Hi Pastrychef,
I've tried injecting these IDs (obviously each number 1 by 1) under Devices in config.plist
1, 2, 3, 5, 7, 11, 13, 15, 16, 21, 27, 28, 29, 34. I got these from acidanthera's GitHub page under
ALC1220. In the Mojave setup this was ID 2.
When I plug the Hyperx headset into the front of the case (the headset goes into a splitter cable, one for ears, one for mic) Catalina detects them as headphones. Digital Out, Headphones and both Lineouts work.
Under Sound Preferences>Input, there is "Internal Microphone Built-in" but when I bark into the mic there is no response in the Input level bars.
When I plug the same headset into my 2012 MB Pro (without the splitter cable) Under Sound Preferences>Input,
Internal Microphone Built-in changes to "External Microphone Microphone port" and when I bark into the microphone there is a response.
Thanks in advance
