UMIK-1 not recognized by REW (on Ubuntu 20.04)

[maxime.levesque]

My Linux OS recognizes the UMI-1:

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: CX8200 Analog [CX8200 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: C920 [HD Pro Webcam C920], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: U18dB [Umik-1 Gain: 18dB], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0


But when I start REW (version 5.19), and go to the edit/preferences dialog, in the Sound Card preferences tab,

the drop down for selecting the sound card shows only "defaut device" and "Pulse Audio Mixer".

I have also tried another sound card that recognized by the OS, and REW does not see it.

any clues on what migth be wrong in my setup ?

Ok, I found the problem.

In the ~/REW directory, there is a log file named roomeq_wizard0.log.txt, produced by REW, and the content was:

I googled "java.lang.UnsatisfiedLinkError: no icedtea-sound in java.library.path"

and found that my java installation did not have the icedtea-sound library

A reinstallation of java with:

sudo apt-get install openjdk-8-jre openjdk-8-jdk

solved the problem

Sounds like you might have had a headless runtime installed, which doesn't include audio support.
