I register my audio input using alsa_in (I named it “phone”), and in Ardour, I make an audio track, I route “phone” to the input of that track. It works, I can add plugins, adjust its volume. But something weird starting to happen when I record that track (by hitting the red record button of the track), the volume I set before not work, the plugins also are being ignored.
Btw I am also using Jack for the main audio interface, but Jack can only using 1 audio interface for input/output, cannot use 2 audio interfaces for input at the same time. In my case, I need 2 inputs. So, I register another input using alsa_in and call it in Ardour directly, but it does not really work as expected. Audio tracks with input from Jack work well. Any help, please?
