I do not know your OS. I can right-click the speaker icon in system tray > recording devices > right-click there > show hidden devices > right-click the Stereo Mix > Enable. I can also check its properties there. Then I can select the Stere Mix source within Open Media dialog in VLC: Capture Device tab > DirectShow > Video device name=None, Audio device name=Stereo Mix (...
You can prepare a batch script starting 2 VLC instances with CLI options.
