I am owner of
Behringer UMC202 audio card and i want to get it working with my Ubuntu 14.04 PC. There is no official support for this card on Mac or Linux (probably).
If i connect device to my PC (with a USB connection), i can see
u96k interface appeared in
System Settings > Sound. But i hear nothing from analog output of UMC202, and cannot receive any signal. I only hear short 'tick' or noise sounds then i turn PC on or reconnecting device. LEDs on my card are all OFF after a while, except the
My card has two mono inputs (or stereo one) and two mono outputs (or stereo one), but i also see
S/PDIF output in
I have found that
jackd is required for my case, and installed packeges
qjackctl. But problem is that if i open
qjackctl and set it to use
u96k interface (using
Settings) it won't start then with this output:

I really want to configure this card to use with my ubuntu pc, otherwise i will have to go back to Windows. I am sure that it's even possible sometimes to use windows drivers for Linux systems, but this is too advanced for me alone..
UPDATE Somehow i've started jack server, but do not hear anything or cannot check it. UPDATE 2 Still does not work... Please help if you can...
