When I posted "The option to reduce the volume might be all that is needed", I was referring to BTB's posted suggestion of lowering the volume of the coin sounds only, not reducing the PC's entire volume setting. Obviously the request is to reduce the loudness of a potentially annoying sound without simultaneously reducing all other sounds and music in the game (otherwise, you'll be constantly playing with your PC's volume each time you enter a coin heavy area or are about to hit a multiple coin block). Adjusting the volume of the coin sound as an option doesn't have to mean a lot of extra sound programming. It could simply be a new coin sound effect file which already has the volume reduced that is uploaded and then selectable as an option. Also, if GB/SNES SFX are ever implemented (which I've already requested) that would allow a couple more options for coin collect sounds.
