Some soundcards have a pc-speaker input on them.

Yes that's what I use on my old boxes. Most Sound Blaster 16's and many other cards have a 2-pin PC-SPK input although you might have to make up your own cable, since most motherboards have a 4-pin wide pc speaker connector. Also if you get the polarity wrong it won't work. Seems like only one pin on the sound card accepts the signal, while the pc-speaker itself will work regardless of which way its plugged into the motherboard.

I believe that wiring the speaker through your Sound Blaster, will get the best result in terms of quality.

The PC speaker amounts to a rather ordinary-looking speaker with two wires coming out of it. You could probably connect whatever you wanted to it. Why you would want to do so is rather beyond me, as the vast majority of games that use the PC speaker don't do anything other than output excruciating beeping noises.

I suppose you could try to connect something that digitally re-samples signals sent to the PC speaker to make them sound more interesting, but that that would not be remotely simple.

Is it possible to make this mono speaker stereo? Or isn`t it worth it.

No games are programmed to output stereo sound through the PC speaker. The best you could do would be to hook a second speaker into the circuit, such that you'd have two speakers making exactly the same sounds, though that hardly counts as "stereo".

Thanks, I didn't even know this!

Is there, by any chance, a compiled list of which audio cards support this option?

Most of Creative's ISA cards have a PC speaker connector. It has a few problems though:
The input volume is too loud and the mixer chip has only four settings to control the volume (0/33/66/100%). Also, connecting the mainboard speaker output to the sound card introduces a great deal of noise.

True. However, there are some integrated sound cards (the particular one I'm speaking of is from SiS730s MoBo) that do this automatically. On that board there is no pcspk pin - it outputs everything directly to speakers; it sounds pretty good too.

Add to that, many (all?) of the Sound Blaster Live sound cards (I have a CT4780 that does).

Wouldn't the AUX or CD input also work? Once you sorted out the right connector of course...

To tell the truth, I wouldn't see any reason why it wouldn't.

Well, if the resistance of the PC speaker is substantially different from the resistance across the AUX pins, that might do something, but I'm not sure if it would really be a problem.

here are some interesting mods:

Ok, i didn`t knowing i could do that.

Is this possible with SB AWE64 gold?

So i need to make an cable from motherboard PC-SPK to soundcard jumper?

EDIT:

Yes i found it on this soundcard behind the cd-in 4 pins connector.
But it is an 2 pins connector..

Where can in find those wires?

Just mod a 4 plug cable. Shouldn't be hard...
