sorry dude i didnt see the private messages(new to this board)
but speakers no matter where they are have to be connected to soundcard's audio output
check the back/side/bottom of ur monitor there should be an audio input hole (probably same as headphone jack on cd players)
u gonna need this cable
as far as audio drivers find a cd that came with ur motherboard
or a recovery cd that came with ur computer
if u dont have any find out ur mobo.s model and go to manufacturer's webpage they usually have drivres and updates and download latest drivers for everything while u there
reinstall the audio driver.
to check unrecognised drivers go here
then click hardware and then select device manager
in device manager if u see any yellow icons thats the devices that either have problems or dont have drivers for them
kinda like this
u can also right click on them and update driver and let windows search online for it (if u have legal copy of windows)
