I’ve noticed that, occasionally, version 2.3.44 loses audio input from any selectable source in the settings. There’s level showing up on the meter right next to the selection, and the “Test” button for output works ok, but audio does not go through to the code. I even tried using the template for an effect, the one with just the gain knob, but audio won’t go through to the code, not from the built-in input, audio interfaces or software buses. I’m using macOS 10.15.4.
Version 2.3.0, though, has no issues at all with that. I’m able to run audio perfectly on the official release.
