I have creative 2.1 channel with sub woofer and 2 speakers (left&right) all of sudden my right speaker is not working left only working then I pluggeg right speaker to left speaker jack in sub woofer it is working what is the problem?

Reverse the silver connection wire from the computer to the box.

I have a similar reoccuring problem with the left channel on my speakers. All of a sudden, while playing music or whatever, the left channel jusr dies. Turning the system off and then on again from the conrol unit does not remedy the situation. By chance, I discovered a workaround to get the left channel working again: Push the main power switch of the subwoofer until it almost switches off and then release it so that the power is never actually switched off. Now a click is heard in the system and the left channel comes alive again. This is quite annoying and seems to have something to do with switches in the subwoofer. Low quality components may have been used. I 've been thinking of getting another 2.1 system, but it's not easy to find one... Maybe I should open the subwoofer box and go through the switches and possibly hardwire some connections...
