Sorry, but if this is not meant as an exclamation but as a question you need to tell us more. What Sonos devices do you own? Why is your music not in sync with your video now?

Thank for the response.  I use the SONOS ARC and an Android phone. On my phone, music and video are synched. I've never know how to see video on TV from the SONOS system. I have seen no button on the app that pertains to video. Cheers

Send the video to your TV.

The Arc, being connected to your TV, will play whatever is being shown on the TV.

You can’t send audio or video from an Android device directly to the Arc. 

Thanks, Bruce.

I can see video on TV from my android phone by mirroring the phone and TV but that has nothing to do with the SONOS app. My SONOS app has no button to press to see video. I don't know if the problem is caused by me or the lack of video screening on the app. 

Sonos does not do video. There’s no way to play video from the Sonos app.

Thanks, Bruce. 

Hello, Airgetlam. 

Your second paragraph nails it down: SONOS does not broadcast video from a phone. 

Many thanks my friend. 

Just to be clear, as ​@106rallye said, Sonos does not do video. Sonos doesn’t ‘broadcast’ anything from an Android, or for that matter, any device. The Sonos app is merely a remote control to see what is happening, and control what is occurring, on a Sonos device. 

Thank you, @106rallye. Many thanks to you and all the others in the discussion.
