Apologies in advance if I break any conventions I am unaware of. I am a long-time musician, but just getting acquainted with audio in linux. I have a very simple goal of getting sound from a plugged instrument to my computer via a usb-interface, the Cakewalk UA25-EX, which I know works with linux. So far the instrument's output is received by the interface, and the interface is recognized by the computer. I asked in the ardour forums on how to get ardour to recognize that the input for audio is the usb interface. <a moz-do-not-send="true" href="https://community.ardour.org/node/15577">They suggested</a> I use ALSA instead of jack to connect to Ardour. The interface of Ardour allows me to select the Cakewalk interface as input and output, but when I play the instrument I see that while the interface gets the signal, the audio is not received by Ardour. If I change the input to my laptop's microphone, then I do get a signal. The problem, then, lies in the connection between the interface and Ardour (or the computer?) I checked the Alsamixer levels and they are not at 0. The advice from the Ardour forum was to contact this mailing list, as I probably need some help checking the connection of the usb interface to the computer. Thanks in advance </body> </html>
