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.
Does the interface work with another computer or OS? Which input are you
using? Instruments should go into input 2 and if it's a stringed
instrument with a pickup and no preamp the Hi-Z button should be
activated. What kind of instrument are you using it with? Could you test
with something else like a microphone?
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.
The interface is recognized by your OS and you can select it in Ardour
or Audacity so I don't think its a connection issue. It sounds more like
a setting on the interface itself. Or a defect but these are very sturdy
devices, I've got an UA-25 that I bought back in like 2005 and it still
works perfectly.
