Hi.
Apparently, the problem is the alsa driver for your card.
check this websites
http://www.alsa-project.org/main/index.php/Matrix:Vendor-MAudio
http://alsa.opensrc.org/index.php/M-Audio_FastTrack_Pro
This websites, say that there is a patch for the driver to suport the
device. maybe you will need to patch de driver and compile it again.
look at it, and if you have some problems come again.
The best
