About installing, it does not look like, that is my problem, because the program is installed I and can open the UC.
Driver version is then 0.0.0.0 - 5875, and I can see the mixer.
Like in Capture / studio one and system pref, I can only se "built-in output" audio device.
About: PaeFireStudio.kext" file is "disabled." You will also notice that the driver might say "No User Consent.
it maybe make sense, but I'm not completely sure, what to do about this ?
Hope someone how about this problem and can help me :-)
