Does anyone have any tips on resolving this? I don't see my KTB in sound preferences on my main desktop (2014 Mac Mini, running Catalina), but I do on my laptop (2011 Macbook Air, not updated to Catalina). I don't really care about it working on my laptop, but need it to work on my desktop. I've tried rebooting a few times with no luck, and I have another DAC working fine via USB on my Mini (Benchmark DAC3 B, which I use on my co-located hifi system). I find this odd.
