Volume Canundrum

[gpurbpur]

Ok so whenever I push the volume button on my Macbook Pro it will make the appropriate little pop noise establishing the volume level.

If I were rapidly press on the the volume up button it would do exactly what you'd expect it to do. It would rapidly make that pop sound, increasing volume each time.

However once I reach the maximum volume, if rapidly press on the volume up button, it will only pop once. I used to be able to rapidly press on the volume up button and get that same number of pops regardless if it was at the maximum volume.

So I guess my question is why is that if I rapidly press on the volume up button at maximum level I will only hear one pop.

If anyone has any idea that would be wonderful. Hopefully I'm making sense here.
