Comment 5 for bug 978895

Sorry Daniel, didn't see your comment. Kubuntu doesn't even hace gconf stuff installed by default, so either gstreamer0.10-gconf should be a required (not recommended) dependency or using autoaudiosink avoids installing gconf packages on Kubuntu (may be the same case for Lubuntu).

I'm not a gstreamer expert, but I'm not sure what advantage gconfsink provides over autoaudiosink.
