mplayer: volume trick

When you want to view a movie or listen to a song which has a squeaky audio the easy option is to use VLC player to set the volume to the max of 400%.

MPlayer by default gives no option for the volume boost. However you can simply make the volume go to any level you want. You just need to set the following options in the ~/.mplayer/config file or the config file in the mplayer install directory on Windows:

softvol=yes

softvol-max=400

Here 400 signifies that maximum volume can be 400%. You can specify any value for this so have custom control over maximum value of the volume.
