Not bad.

I recall a special Windows 3 driver could push sound effects and music through PC speakers, at least those which were an actual small speaker embedded in the case. It was very rough and mono but a neat trick. I don't think it worked with the coin sized beepers in older models.

Used that before, Its basically software PWM and moving the mouse messes with it. There is an equivalent in Linux called snd-pcsp which can be modprobed in case no sound card exists. It has the same issues though

I remember this driver and relied on it for a few years. Was sort of amazing, all things considered.
