Is there a way to play what would normally be played through the PC speaker on a sound card (like driver changes, etc)?  How would you do it (searching and having problems finding answers that don't involve sound card on PC speakers questions)?

I'm not sure I understand the question.

Sound cards don't actually play sounds, they decode the sound and send it through their outputs to whatever speaker is plugged in.

Without the speakers, the sound card has no way of playing the sound.

There maybe a case where the sound card has a built in speaker, but its still a speaker that actually plays the sound.

Could you perhaps explain a bit more what you are trying to accomplish? And what it has to do with Windows ME?

Maybe this might be getting past days for today's computers.  But once upon a time (maybe today, I don't know), there was a PC speaker that would be in the computer.  These things were even in the computers before sound cards were commonplace.

Now with the sound cards, you can play, generally, more variety of sounds.  But it has the cable output to a speaker system, as you described.

Now logically, I'm thinking there has to be a way to play sounds that are destined for the PC speaker (the standard computer way to make sounds) on the sound card, especially when we get to some more complex OSes than DOS (like Windows ME).  I'm asking how to do it.

Ahh you mean the system speaker.

However I'm not sure you can actually use it the way you want to.  
Putting aside the task of getting windows to use it. Once you did, the speaker is not equipped to produce any sort of sound beyond beeps.  So supposing you sent a music file to it, you'd hear just a string of beeps rather than actual music.

Getting Windows to use it is another thing all together. Motherboards don't actually have drivers that let you communicate with it. they just send voltage to the pins it connects to to generate the sounds. Voltage generates a beep, no voltage means silence. So the MB alternates between voltage and no voltage and the length of each status to produce the beeps and beep codes for errors.

You could probably write your own driver to do this, but I doubt there's a commercial one available.
