If you have an advanced button, click on that and adjust the tone control for the bass and treble and deselect the enhancement feature. My soundblaster card is connected to an amplifier as with my synthesizer and I once had that trouble, but lowering the sound in the volume control balance solved that problem as I can control the volume on the amplifier instead. Depending on the sort of music, the enhancement feature can be deselected and get the best sound at times without the enhancement. 'Hope this helps. Iz Kuzara
