if I understand correctly, the Librem15rev2 is equipped with a combo port for audio, and I got my headset working with a Y-cable splitting the combo port into a headphone and microphone connection.
Now I would like to use the microphone connector to record an external audio source (e.g. with audacity), but I just can’t get it to work!
There some source on the web that suggest this should be dead simple (e.g. https://gordonlesti.com/digitize-a-cassette-tape-with-linux/), but in my case, audacity only displays what I would cconsider as random noise.
I have the ‘pavucontrol’ module installed , and I also fiddled with QjackCtl (drawing inspiration from the guide by François Téchené “Your own music studio with JACK, Ardour and Yoshimi” in the “News&Events” section), but there is no way that the external audio source is recognized. At least I don’t get it to work.
Anybody has any suggestions?
