I have noticed that progressively over the past 12 months or so an ever increasing appearance of "voice over" deliveries during my use of the internet.
Always unwanted & characterised by being loud & nigh impossible to shut off; you simply can't tell which site is responsible.
The only defense I have found is to reduce the system speaker volume to zero, which takes a couple of clicks. Then of course you have to remember to restore the volume slider control to whatever is appropriate for your typical use, about 15% in my case.
Sometimes the same sort of intrusion is an unwanted video; but that at least can usually be dispatched by one of the AD blockers. Of course this is an unwelcome waste of time & should not be necessary.
So my question is: how can I set up to allow my PC to recognise this crap & either shut it down promptly or just prevent it?
BTW I have done several Google searches, the issue is "known about", but I can find no reasonably convenient method of prevention.
