Thanks much. I found the problem was a little error in my modules.conf file. Now that I have my card working to its fullest potential, I am having some difficulty with xruns. Most of my projects are rather long recordings but I cannot seem to make ardour work for more than 8 or so minutes before an xrun in jack stops the transport. I have tried the jack startup settings from the wiki (the rme_adat ones) and have not been able to get them to work. I am currently using -R -t 2000 -d alsa -d rme_adat -r 44100 -p 256 -n8 -zs -H -M which seems to give me the longest stretch of recording time. I would like to bump up the period length to -p 512 but jack will not accept anything above -p 256 (64 works though). Any thoughts? James
