Anyway to make LAPTOP speakers louder?
That's pretty common for laptops. But as long as you checked all the "volume" locations, that's about it as far as I know.
From the speaker icon in the system tray. To control panel audio section, make sure the pan is in the middle, that the speakers are set to stereo speakers, and the main volume slider is all the way. All this can be done from in there. But there is more then one location for volume. Also use the laptop's function keys to up the volume, as this can sometimes be sepparate from Windows control. And lastly the volume of the DVD playing software itself, may also be sepparate.
But as far as I know, there is no such thing as a software amp.
