Hello, first of all, i want to thank you for the attention. It's necessary good support recording with Ubuntu, and you do so well.

So, i have the M-Audio Fast Track C400 and i have installed on my computer Ubuntu 12.04 LTS (Precise Pangolin). My system recognized the soundcard, run JACK with it, but i can't record or hear any sound from there.

Which procedure i have to do?

Thank you again.

Best regards.
