How to always start media volume from mute when I am in silent mode?

[acsurfer]

Hi,

I put my Samsung Note 8 to silent mode and when I play any videos in browser/youtube/facebook, the media volume would still have sound.

I want to maintain in silent mode all the time and I want to the media volume to default to 0 (mute) every time when a new video started playing (I may manually increase the media volume after a video started playing).

How can I do that?

Thanks

(By default, if I put my phone to silent mode, only the ringing is changed to vibration and any video played will still have sound.)
