The application is working well on my KDE-based laptop where it appears that the application is using Phonon -> ALSA -> PulseAudio. But there is no sound from the application when run on the PS3. BTW, the base software on both systems is Fedora 9 but on the PS3 I'm running a kernel downloaded from git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-linux.git. The kernel has both ALSA and OSS compiled in. Using the following /etc/pulse/default.pa file I can get output from aplay, paplay and mplayer (the latter with "-ao pulse"). === begin === #!/usr/bin/pulseaudio -nF .nofail load-sample-lazy pulse-hotplug /usr/share/sounds/startup3.wav .fail load-module module-oss device="/dev/dsp" sink_name=output source_name=input load-module module-hal-detect load-module module-esound-protocol-unix load-module module-native-protocol-unix load-module module-volume-restore load-module module-default-device-restore load-module module-rescue-streams .ifexists /usr/lib/pulse-0.9/modules//module-gconf.so load-module module-gconf .endif === end === (Yes, I realise that I have loaded the OSS module as without it I get no sound at all!) The following is the output from the pulseaudio daemon and as you can see there are problems with the pulseaudio / alsa interface. === begin === # pulseaudio -vvv --system I: core-util.c: Successfully gained nice level -11.
