Hi all I installed kernel-2.6.10-1.766_FC3.i686, every thing works fine on GNOME but on KDE if I want to lunch Realplayer10 it Hangs for a minute and then it starts but I can't hear nothing at all, I used sound card detection it did the same thing , for example on xmms it wont play at all, I get the message that sound device maybe busy... Any help please. Many thanks Ameur Mohamed
