Hi, I'm one of GCompris' maintainers. Thank you for packaging it!
>From time to time, we have feedback that there is no sound when playing with GCompris. Most of the time, it is because the gstreamer1.0-plugins-good and gstreamer1.0-plugins-bad are not installed. Would it be possible to add it as dependency/recommandation or suggestion (I'm not sure which one would feel the better)? Cheers, Johnny
