USB Card, no sounds

Hi,
Is there a way to make a USB soundcard working. I tried to configure it with an
alsa upgrade, but there's always an error message ending the process. Do I need
a complementary module, like a hotplug for connections. In theory, my card is supposed to work with Kernel 2.6.22, but not detected unless I use Gnome 2.20. Sometimes it says that I'm missing the Gstreamer codec.

Thanks.

USB support

Hi sirven,

What USB device are you using? If it is a properly designed device, it should be class compliant, and then the device should be picked up by the system hotplug automatically.

Info

The card is in the list of compatible soundcards on the alsa website.
For automatic detection,under Ubuntu, it says missing the right Gstreamer files.
In 64 Studio, except in Jack, the card doesn't show up in the sound panel.

My configuration ;
NI Kore I USB soundcard (audio and midi fonctions)
64 Studio (32bits)
Intel Core duo 2.13 Ghz
MainBoard - MSI 945GM3 Series
2000 mb RAM

It's jacked!

Ok, if it shows up in jack (and you can play sound to it via jack) you could try to configure your usb card as device 0 - see the user FAQ number 10

Your first two lines will then be:

alias snd-card-0 snd-usb-audio
options snd-usb-audio index=0

add the other devices trailing this one.

Card-0 is the default playback device for normal alsa stuff, and this should do the trick

Let us know,

Cheers

In Jack

I tried your suggestion lately. Still Jack can't get starting with the USB card.
By the way, I have to mention that I could install Alsa-driver 1.0.15, but
not Alsalib, that still give error when compiling. I there any other ways to update drivers ? The module I need is usb-audio and usb-caiaq. Thanks

The error message from Jack :
