I noticed the delay as well (Dell 8200 with addition Santa Cruz sound card). What I've done is decided to use ALSA, my own xmms build, and use an external player in sound notifications for those programs that use the KDE sound notification system. Right now I'm using aplay from the ALSA utilities as the external sound player for the notifications. This seems to work well with two exceptions. 1. I cannot use .ogg files. I have a really nice sound theme I would like to use, but they're all in .oog format. 2. Once you enable an external player in the KDE Control Center Sound and Multimedia --> System Notifications, you cannot change that value via the KDE Control Center. You have to go into the knotifyrc file and edit it by hand to make changes. I've mentioned both before, and I should probably post a bug on either Fedora or KDE (or both). Other than those two glitches, running without aRTs is working well. My next goals are to get Jack running on Fedora Core 2, then the appropriate environment for MIDI music composition . . . . when I have the time. /mde/is just my two cents . . . .
