Hi there,
I’m trying to get audio in from my sound card and route it to the main output using the tracktion engine. To learn how to do that I checked the “Recording” demo of tracktion. However I seem to have some problems because not even that demo app is recording properly for me. I can compile and run the “Recording” app properly, however even if I configure my sound card in the audio settings and enable tracks for recording, I only see silence in the output. The screenshot below shows how I have everything configured but I only record silence:
(I was sending signal to input 1 so I should see first track waveform with some action)
In fact, in the audio settings panel, below the test button, I never see the levels indicated there, even if I switch to Built-in-microphone which should definitely work. That looks like a bug but I don’t know what else to check 
My system: macOS 10.14.6, Juce 5.4.5, tracktion @ https://github.com/Tracktion/tracktion_engine/tree/c686909a062a44171c0215cc8a0c1fbbcc320a95
Audio inputs work well in other software I use (Bitwig, Logic), so should not be a soundcard issue.
Any ideas?
Thank you!!!
