Need help Plugins

Hello, I would like my two videos to play their sound at the same time. The idea is that I want to play the sound and audio of video 2 and only the sound of video 2 (I reduce the size of video 2 and that way I only have the sound of 2), video 2 is a YouTube video.
Thank you for your help.
