Behringer ASIO audio card in Ubuntu
You should not need JACK, audio interfaces supporting the USB audio standard (all versions) should work without you having to do anything. In fact, installing JACK may very well be the source of your problems. Usually it is the other way round: USB audio devices work on Linux out of the box while drivers are needed for Windows.
The most frequent problem is that one of the channels is muted or at a low volume, or that JACK is messing things up. So my suggestion is:
- Undo everything you've done, including installing JACK.
- Unplug the sound card, reboot your system, login and then plug the sound card back in and select it from the sound settings.
- Install and run
pavucontrol
(a GUI tool) to see if anything is muted - Then also run
alsamixer
(from a terminal) to check any other channels. In alsamixer, press F6 to select your sound card, then F5 to show all channels. Check that none have the muted checkbox set. Press M to mute/unmute channels.
If it works after these steps, and you are sure that you absolutely need the (possibly) lower latency that JACK provides, you can then always go and try using the device again using JACK. But you should make sure that the device works beforehand.

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 inSystem 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 thePower
one.My card has two mono inputs (or stereo one) and two mono outputs (or stereo one), but i also see
S/PDIF
output inSounds
dialog..I have found that
jackd
is required for my case, and installed packegesjackd2
andqjackctl
. But problem is that if i openqjackctl
and set it to useu96k
interface (usingSetup
button,Settings
) it won't start then with this output:08:12:32.111 Patchbay deactivated. 08:12:32.125 Statistics reset. 08:12:32.149 ALSA connection change. 08:12:32.161 D-BUS: Service not available (org.jackaudio.service aka jackdbus).

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...

Croll about 9 yearsAfter few days of hope... I did anything i can imagine. Actually, this page saved me: askubuntu.com/a/150932/383077, somehow, i didn't notice before, that
alsamixer
shows output channels are MUTED, regardless their volume set maximum. To unmute i had to pressM
key. To select my card, i usedF6
inalsamixer

Croll about 9 yearsThank you very much. But could you tell me how do i control sample rate and asio buffer size? Do i have to use jackd for that?

Matthis Kohli about 2 yearsIf the problem is the input not being recorded then I suggest in the back do toggle the +48V button which solved the issue for me after going through all software configuration steps mentioned in the internet :)
