[Alsa-user] C400

[iago <ia...@or...>]

I already installed latest release of KXStudio with 3.8.0-28-lowlatency 
#20-Ubuntu SMP PREEMPT.
My FastTrack C400 is now recognised by alsa but still doesn't works.
The Jack message tells :

I also modified alsa-base.conf by commenting the line options 
snd-usb-audio index = -2


Thanks
