Hi,

I am looking at the documentation for my M-Audio Fasttrack Pro and it
can do up to 96k 24bit recording, however, I am trying to fire it up
with qjackctl and it I can't get it to do anything other than 16 bit
little endian 44100 sample rate.  I get an error in the messages that
says the playback and capture sample rates do not match.

I am using the latest Ubuntu 10.04LTS with 
Following are my "messages"
Does anybody know how I can get the most out of this device?

Thanks
Rick
