Using pulseaudio by default

Since one of the plans for better sound in FC7 involves replacing esound by pulseaudio, I had a look at this problem today. First there is a wiki page about transitioning the gnome stack to pulseaudio (http://live.gnome.org/PulseAudio?highlight=%28pulse%29) which as some white spots, so there is some work left to do - it may be possible to get there quickly for now by making use of the fact that pulseaudio has esd emulation, and worry about cleaning up libesd dependencies later. Is that the plan for FC7 ? What is the plan for gstreamer, use the pulseaudio alsa emulation ? Then, I installed the current Extras pulseaudio package, and found that it does not work :-(. Trying to run pulseaudio yields: main.c: WARNING: called SUID root, but not in group 'pulse-rt'. module-hal-detect.c: failed to detect any sound hardware. module.c: Failed to load "module-hal-detect" (argument: ""): initialization failed. main.c: Module load failed. main.c: failed to initialize daemon. Judging by the error message, pulseaudio seems to use some debianesque manage-by-groups scheme. Indeed, looking at /etc/group, the package created three groups, "pulse", "pulse-rt" and "pulse-access". But why are these created in the range of regular user-groups, and how does one use them ? I couldn't find any documentation about this in the package. Clearly, some work is needed to make pulseaudio-based sound work out of the box. Matthias
