I'm trying to hook my motherboard's external speaker jack up to my Sound Blaster 16 (CT1740) so I can play the PC speaker through the sound card.
My motherboard has a jumper for disabling the internal speaker (a buzzer). That is set to disabled to activate the external speaker 4-pin header. The manual says the pinout is:
pin 1 speaker
pin 2 key
pin 3 ground
pin 4 +5V
My SB card, however, has a 2-pin header for the speaker input. I believe its:
1 +5V
2 ground
How do you get 4 signals down to 2? I've never seen a cable that will do that anyway, I guess I'll just have to modify a CD-ROM cable (the that connected older CD-ROMs to the sound card, inside the case)?
