I caught myself wanting to make a cross-tab sound controller and i have done some research on this, but i can't really find a good way to go about controlling the sound for all elements in all open tabs.
Does anyone know of any way with jq, js, or anything else that can run in a browser that can be used to controll the volume of all open (and new) tabs?
The use-case would eks be muting all tabs with one button, adjusting up or down the total "browser volume" in one place, and such.
I haven't been able to find any support for this so far, so does that mean it really is impossible after all?
Edit: The main thing is that this needs to be "cross-tab" and not just a way to adjust a single audio player / audio source playing in a single tab. Say you have 5 tabs with Youtube open and i want to be able to mute / lower volume / raise volume of all those tabs from one single tab.
