I wish such shenanigans would simply trigger the little speaker icon most browser display on tabs these days.
Given that they don't (at least in my experience), I'm assuming "playing silent audio" is a sufficiently common thing for websites to do to have motivated browsers into doing the slightly more complicated thing of actually analyzing audio streams for content...
Now I wonder, does this also allow websites to continue running in the background on mobile browsers? Playing media is one of the very few things that can convince iOS Safari to keep a tab running indefinitely, in my experience.
