Split video and audio to play on a projector and sonos

[Counterfitninja 6]

Hey There, 

I have a Mini projector and a sonos bean gen1 that i want to use to show a film at a community event. 

Is there anyway to simply send the audio to the sonos via the sonos cast function but have the video still play?

Lots of advice and articles in this search that find answers for audio playback.
