Mute video/audio playback before it's played.

### Your use case

#### What would you like to do?

I wish that I can turn off the volume of a shared video/audio before it's played.

Currently, if I click a shared video, I can't do anything until it starts playback -- **in full volume**, which really scares me over and over again.

My partner gets scared, too. This frustrating post was after an argue.

#### Why would you like to do it?

Because I don't want to get scared anymore, and so does my partner.

#### How would you like to achieve it?

Either add a config to mute all objects potentially sound, or make the volume bar adjustable before I click to download the video.

This really helps a lot and will save me and my partner and more people's lives.

Thank you.
