There is a
bug on some computers where there is a faint clicking or crackling sound when playing audio. This can often be fixed by going into the mixer and muting the Bass Boost (or just turn the volume of Bass Boost all the way down). If you don't see Bass Boost in the mixer, look at the Properties area of the mixer and make sure the checkbox is checked for Bass Boost.
Another possible fix for this problem is to go into the mixer and lower the volume of the "wave" slider. You can then increase the volume on your speakers to bring the listening volume back up again.
By the way, SoundMAX requires DirectX 8.1 or greater. You can download DirectX from the Microsoft website.
