Send audio from mediaplayer through metasound

Hi This may well be a newbie question I am completely new to Sound classes etc. I have a scene with various bits of video I want to send the audio from those to specific speakers. I can do sounds to speakers through meatsound amd wave players but can’t work how to send the audio from the video - Is this even the right way to go? If so how, or what should I be looking at?
Thanks

Have a look at audio bus and source bus , if I understood your needs correctly they are the way to go
