The speaker can be plugged in either way around. Both ways work the same. I like to have a speaker, so that I can hear a friendly "beep" when the machine boots. Apart from that, it is not used much..... Some BIOS manufacturers use to to "beep" error codes if there is a fault on the motherboard (e.g. like the CPU overheating).
