Patrick: Thanks for responding to my pleas for help! I run Red Hat 9 (moving to Planet CCRMA Fedora Core soon). Rate is at 48000, but I do use period size of 512 (maybe that's the problem). The /tmp directory I have never changed. Thanks for this tip. I will try it and hit you back. There is not much info out there (or I'm probably looking in the wrong place) regarding a proper setup of the /etc/modules.conf file. I could sure use some insight into this file. Thanks again Patrick, gk
