Google Chrome adjust volume per tab

Is it possible to adjust the volume of individual tabs in Google Chrome?

I've found an extension that allows the volume to be muted, but it does not allow variable volumes.

UPDATE Years after asking this question, it looks like a solution is finally available!!! @peta-sittek created an extension to perform this exact function!

Sounds like Volume Master (Chrome extension) does exactly what you want: https://chrome.google.com/webstore/detail/volume-master/jghecgabfgfdldnmbfkhmffcabddioke

You can active one of chromes flags on chrome://flags

Simply enable the called: Tab audio muting UI control. This works for Mac, Windows, Linux, Chrome OS.

Then if you're using an old browser restart Chrome but on newer ones simply right click on the tab and the option to mute the tab should be there.
