Play VideoTexture's audio only

I have a video with an audio track.

In one situation, I don’t need to play the video, just the audio. So I’m trying to play the audio track that is associated with it.

If I make a normal AudioSource and choose the clip as the video’s sound clip, it doesn’t play.

I think the sound clip’s playback position is tied to the movie’s playback position.

I’ve tried dragging the audio clip from being a child of the VideoTexture, to being on its own within the Project Tree but that doesn’t work.

Does anyone know how to break this link, or how to play audio without having to play the video?

possible workaround - put the movie texture on a plane that’s facing away from the camera so you don’t see it. unless the renderer is clever enough to know it’s invisible all the time, this should work.
