In spite of all the assurances that the sound problems I was experiencing in FC3T3 were because I UPGRADED from FC2 instead of installing fresh, I still have no sound in FC3RC3. I installed FC3rc3 fresh, partitioning the drive several times. (I'll discuss that later.) Same symptoms too: arts going nuts, system-config-soundcard hangs, etc. See my post from yesterday on the same subject. I think this issue needs some attention. I submitted a bugzilla report on it.
