I have installed both alsa and jack. do you suggest that I should uninstall alsa and use oss? Because other sources suggest to use alsa together with jack. But, I guess this is a really newbie's question, do I have to do anything everytime I want to use jack with a program like snd? I use fedora c7 with the planetccrma kernel, so I always thought that everything is configured since I use planetccrma. I did search in the web to find how to configure jack in fedora but got even more confused.
Does anybody have any idea about the clm problem? this is more important for me at the moment.

I guess using a different sound API than alsa should solve problems like
that. OSS and/or jack should work fine.
