Is it possible to mute any sound from a tab via vanilla JavaScript?
Briefly

While JavaScript provides control over audio elements via the DOM, it doesn't extend to muting all sounds from a browser tab, as browser settings govern ultimate audio output.
Muting can be handled through specific methods like pausing or removing audio elements, but any global muting mechanism would need higher access beyond JavaScript's capabilities.
