Thanks Sebastian, we have just red this message: we apologise for not answering before! we actually realised that the problem was the audio activation: while for conferencing openmeetings explicitly asks for audio/video activation, it doesn't happen for sharing/recording; so we didn't think to such solution... It was too trivial!!! Maybe you can add this "suggestion" when clicking on screenrecording.
