The 2 seconds would be a bug or maybe a design fault in his computer. I use a big USB volume knob [1] which is also a mute button and it always responds instantaneously as far as I can tell. I just bash it when an unexpected video starts playing. It was hard to find but these things do exist and are refreshingly convenient compared to whatever fiddly volume controls laptops always have.
