I don't know what I have done now, but suddenly sound stopped working on my desktop fc8 computer. I must have changed some setting ... I'm getting this message in /var/log/messages whenever I try to play anything. Can anyone tell me what this message indicates? pstream.c: Recieved SHM frame on a socket where SHM is disabled. pulseaudio is running as this: /usr/bin/pulseaudio --log-target=syslog .nofail load-sample-lazy pulse-hotplug /usr/share/sounds/startup3.wav .ifexists /usr/lib/pulse-0.9/modules//module-hal-detect.so load-module module-hal-detect .else load-module module-detect .endif load-module module-esound-protocol-unix load-module module-native-protocol-unix auth-anonymous=1 load-module module-native-protocol-tcp auth-anonymous=1 load-module module-http-protocol-tcp load-module module-zeroconf-publish load-module module-null-sink sink_name=rtp format=s16le channels=2 rate=44100 description="RTP Multicast Sink" load-module module-rtp-send source=rtp.monitor load-module module-rtp-recv load-module module-combine sink_name=combined master=alsa_output.pci_8086_24d5_alsa_playback_0 slaves=rtp load-module module-volume-restore load-module module-default-device-restore load-module module-rescue-streams load-module module-suspend-on-idle .ifexists /usr/lib/pulse-0.9/modules//module-x11-publish.so .endif .ifexists /usr/lib/pulse-0.9/modules//module-gconf.so load-module module-gconf .endif set-sink-mute rtp 1 Thanks, Jim
