I have this recurring problem ever since I had my first laptop. The speakers on laptops are usually quiet but usable, however there are some sound sources that are even quieter than normal, be it Youtube videos, movie files or mp3, some are unbearably quiet.
I realize that programatically boosting all computer sounds would result in terrible crackling etc, but I only need it rarely and on demand, when listening to a weak sound source. Is there an application for that.
