Using "Copy audio:" in multiview stream doesn't copy audio. Nothing about this in the documentation, but a work around is that you go into the stream to provide audio and create a stream process to target the multview stream itself to inject audio, requires a delay >=15 seconds and requires "always on" for multiview stream to ensure its available to have the audio, otherwise the UYVY track is never added if audio is added first.
