[LAU] Help getting sound from Cakewalk UA-25 EX to Ardour

[Hernán Labbé Grünberg]

Hi everyone,

This is my first email to this list. 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. They suggested <https://community.ardour.org/node/15577> 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
