 Audio underrun information could be used to form a cross-site
 covert channel between two cooperating sites.
 One site could transmit information by intentionally causing audio glitches

 It typically requires a shared linearization point (such as an OS or browser
 audio mixer) and callbacks that are effectively synchronous from that point,
 without intermediate buffering that would flatten load spikes.
