I have PulseAudio enabled on my KDE installation, and the sound is working just fine. But I keep getting these strange messages in my /var/log/messages file:
Jan 12 14:05:35 kevin-pc rtkit-daemon: Sucessfully made thread 4882 of process 4882 (/usr/bin/pulseaudio) owned by 'kevin' high priority at nice level -11.
Jan 12 14:05:35 kevin-pc pulseaudio: [pulseaudio] main.c: Daemon startup without any loaded modules, refusing to work.
Jan 12 14:05:35 kevin-pc pulseaudio: [pulseaudio] main.c: Daemon startup failed.
Those last two messages don't sound good to me. But, like I said, the sound is working just fine.
