Hi CCRMA, I'm new to Linux audio, just installed Fedora 5 on my laptop, instaled PREEMPT_DESKTOP kernel and some other packages. Everything looks very promising. Now I need to configure ALSA to work with my Echo Indigo I/O card. In order to do that I need the sources (or at least the headers) for my kernel. So where I can find the PREEMPT_DESKTOP sources? Thank you, Dima
