PC speaker to sound card routing software question.

<< < (2/3) > >>

krick:
don't know about your specific sound card but just about every sound blaster card I have ever seen has a 2 pin connector on it labeled "pc speaker".    You just connect the 2 pin speaker output from the motherboard to the connector on the card and sound comes out through the sound card output.

I'm not positive but I think you may also need to go into the mixer (double click on the speaker in the tray), under the options-> properties menu, enable the display of the PC speaker, and un mute it.

Well, there isn't a specific sound card, this is using the onboard sound on a Shuttle AK38N mobo.  There are two CD-Audio inputs, and the link I posted above explains how to connect into this using a standard cable and a capacitor and resistor.  I'm tempted to see what would happen just running a wire from the speaker output to this, but then again, don't really want to fry the mobo. . .

PC Speaker is unmuted already.  Sound works through the PC Speaker, it just sounds bad (not sure the external speakers will sound much better?), and lacks a convenient volume control . . .)

If you have onboard sound, I don't think you have any real options other than that link.

The PC speaker output on your motherboard is already amplified to drive the PC speaker.  I wouldn't hook it up directly to the aux input.   That capacitor/resistor circuit is there to drop it to line level to protect your motherboard.

If it sounds crappy now, it will still sound crappy.  You will have a volume control, however.


Too bad you don't have a motherboard with a CMI8738 chip our you could do this instead...

Or I suppose I could shell out $13 for this and use the mono input . . .

krick:
Personally, I'd buy a soundblaster PCI card that has the 2-pin "PC Speaker" input.

Then you can just make the connection with a simple 2-wire cable.  No soldering involved.

I believe it also converts the pc speaker input into "dual mono" so that it comes out of both speakers.

I'm not sure what specific SB models have this 2-pin input but I'll start looking and see if I can dig up a few.
