    I have two samson resolve 50a speakers that *hums* when connected directly to the back of my presario computer (through a 1/8 inch to two rca chord). However, when I connect them directly into my ipod or mixing board they don't hum and they sound great. Meanwhile, if I listen to headphones through the out jack of my computer I don't hear a hum.

    How can I connect these great speaker to my computer?

    The "hum" indicates a poor earth connection on the sheild of the cable, or an "earth loop" where the ground of the computer is not the same as the ground of the speaker amplifier supply.

    Most likely its a connection issue somewhere.

    You may be plugging the speakers into an amplified output, try the line-out or headphone-out.
