you can buy a usb powered 5.1 or 7.1 sound card from best buy or other store but you dont "need" to have a amp or reciever i use one for games but its not needed just the 5.1 sound card or 7.1

the audio out jack on the mini is also optical, you will need some sort of amplifier that will take an optical input. (can be in powered speakers, but you sill need an amp)
