I did a live brodacast this past Tuesday. I would like to offer another solution that you can consider. This would be an option if you care more so about the AUDIO as opposed to the video. I pulled up each YouTube video in a separate window. Then, before clicking the video to play, I created a full screen, generic overlay with the description of the YouTube video on it. I left the overlay up until the video finished playing. Once again, this is an option if you just want to hear the audio. Otherwise, you can do as the Livestream support team has suggested. Take care.
