Dear guys and gals, I have a problem with Moto Racer 1.

I am trying to adjust effects volume (basically the sounds of the bikes) independently from the music and master volume.
Sadly when I try to do it from the settings menu, all three volume sliders move in unison.

I also know that pressing F1 in game brings up a lot of commands, but even then only the master volume is affected. The game shows that I am adjusting different volumes when I press the different key combinations, but the end result is always the same: every single volume is affected.

This makes me so sad! The soundtrack is great and I would like to be able to hear it during races!
