Volume control hack
(1/2) > >>
MrToasty:
I was watching TechTV the other night and they demonstrated a hack to control a PCs volume with external hardware.  If you have a Sound Blaster Live, you can essentially wire two buttons directly to a header on the board for volume up and down.  Here's the link:

Not sure if this has been covered here already, but I haven't come across it before.

Wow, that could really be useful.
Dak-ak:
soundblaster live value cards lack the headers, but they have the spot for the headers on the pcb (cheap ---daisies---, its probably close to .0005 cent per card).  anyways, i was able to set my live value card up for this without too much trouble (just soldered a header onto it)
canardo:
cheers for the info shame in my cabinet I got a built in sound card might have to put the live from this machine in there now hehe
Beley:
What that article failed to mention is that if you hit both of the buttons at the same time it will mute/unmute the audio
