Thanks Thomas You did help. Your advice led me to bug report. https://bugzilla.redhat.com/show_bug.cgi?id=537986 because the sound card as indicated with the chipset "conexant 5067" was not yet supported. Your advice about setting the hda-intel.conf was right on the money. And after I installed the latest alsa-driver as per advice from the bug report everything worked.
