Hey there, we've installed Greenfoot on multiple linux systems which haven't any audio installed (PulseAudio isn't available). This results into the following error message and StackTrace: https://imgur.com/a/WVUxV I started the "LunarLander" example scenario. When the rocket crashes it shows the first error message. After clicking on "Reset" it shows me the stacktrace. That's very annoying when this message pops up everytime you Reset the game. Is there a way to disable sound globally in Greenfoot so this messages will be suppressed? I don't want to modify the source code of the example scenarios and delete the audio part. Maybe you have an idea how to solve this? Thanks in advance
