hi, my current 4.1 speaker system stopped working (it was a cheap one from a computer fair, had it about 4 years).

so i purchased another 5.1 set today (made by Tevion, 50W RMS).

i have plugged everything in, led comes on the subwoofer, but no sound.

i went in to Creative software on my pc to do the "5.1 test" where a woman says the name of each speaker, but no sound.

any ideas?
