USB sound cards are effectively free.

I don't know whether there is a standard for USB sound cards, or whether you have to buy a particular one though.
 
I was suggesting USB over forking out for PCI or developing a PCI express solution. For PCMCIA it would make sense for someone to write a driver, but I expect everyone uses PCMCIA for networking these days.

Yepp they work well enough, bought one for one of my servers that didn't have built in sound to use sound alarm for some events
