hi, installed FC3, did Yum update... using KDE/XFCE/Gnome is the same: sound is hissing; controls not working: "aumix" sliders have no effect?! (sound was fine in RH7.3 and RH9 using same original SB Live! card). Found in "Kmix" a new option called "switches", and if unchecking "IEC598 Optical Raw" the audio is muted (played with the settings according to http://www.linux.com/article.pl?sid=04/06/24/1638255, and http://fedoraforum.org/forum/showthread.php?t=26267 , which worked for me in FC2, but not now... Where to go from here? mp -- Take control of your informational flow! Join a community server: http://wiki.aktivix.org
