timppu: Ah, the good old times when you'd run a DOS game in the middle of the night, and then the whole neighborhood would hear the music: "BEE BOO BOO BEE BO BE BOO BOO BE BOO BO BE BOO,..." (that was the title tune from Leisure Suit Larry, by the way). And you reaching for the power button of the PC to turn the damn loud infernal machine off.
It was like some space age high-tech later when some sound cards offered an option to reconnect the beeper cable to your sound card, so that the sounds would come through your speakers instead (so that you could indeed apply also volume to them).
We had a volume button build on the pc itself to lower it.
