I tried to connect NI Komplete Audio 6 USB audio interface. I changed an audio interface from HiFiBerry to USB by web interface… and no success, no sound… Did I miss something? Thank you, martin
I never tried this device. You should see (google) if it requires some specific configuration with Linux.
It is Class Compliant device, so I expected a smooth implementation… I ll check linux issues on web.
Found that alsa supports that card… https://alsa-project.org/main/index.php/Matrix:Module-usb-audio
Zynthian default configuration is for 2 channels (stereo), so probably you have to do something with it. Perhaps tunning the jackd options in webtool, etc.
Thanks. No idea how to do that
Try to get it running in a standard rasbian environment.
After that we can figure out what information we need.
Thank you. Could you please be more specific? I have no idea what to do. I understand, that I should change the SD card and run Raspberry with the standard OS, but then whan?
I am also fighting with an external sound card to input my electric guitar signal to Zynthian. I am using a really cheap one and I got it apparently detected and accessible for the system.

The “USB PnP Sound Device” is the new audio card, Device 1. A25 is the MIDI keyboard that I have also plugged, Device 2. Device 0 is the HifiberryDac+, which is working fine.
I can control the volume of all the devices via Alsamixer. What I cannot do now is to process the input of the guitar… In fact I don’t know how to do it…
I would like to be able to do it via MOD-UI but I cannot see the USB sound card as an audio input in the left of the pedalboard on the web interface. Do you know if the MOD-UI interface can be configured to use another external card?
Any suggestion please?
In MOD-UI there is a small sign in the bottom line, where you can click on and add additional IOs.
Thanks for the response. I am looking for the sign but I do not find it.
I can see the MIDI ports (two USB keyboards) but not the new sound card attached via USB (which seems to be recognized by the system).
Hmmmmm… the “sign” was the MIDI-DIN connector icon
Strange. Perhaps your USB card is not recognized by a linux system? Can you “ssh” to the Zynthian and look at
/var/log/syslog or with
dmesg if linux can “see” your card?
Hmmm, maybe I understood something wrong… sorry. You cnnot add more audio inputs/outputs on the fly with MOD-UI. You only can add MIDI I/O… sorry.
Exactly, I cannot add the new analog audio signal from the new sound card into MOD-UI. Maybe I am trying something imposible (which is not unussual, I am a scientist… ).
It is detected by the system, I can even change its values via Alsamixer. Maybe it is related with the jackctl initialisation command.
Many thanks for the help. Best regards,
