SHould be depending on your audio card and if all the drivers are installed.
Go to control panel, sound and audio drivers, sound and audio device properties - press Advanced button, master volume screen - advanced button.
Whew, now you should have a advanced master volume screen with bass and treble sliders to play with.
Or if you have the speaker icon on your toolbar double click that and the msater volume panel should come up. Hit the advanced button.
If that does not work many of the audio music players have built in or add on graphic equalizers where you can boost any part of the audio band you want. I use a DFX add on.
