I have a Logitech 5.1 Surround speaker system for my desktop PC, and lost the owners manual. Black, Yellow, and Green connectors for the Surround system, but the computer has Pink, Green, and Blue. I've only ever used the two front, the center, and subwoofer. Never use the rear speakers because there's no way to place them behind. How I have them connected seems to be working, but I don't know if it's right...

How did you connect them? Also, couldn't you Google your speakers to determine which connections are which?
Connected Yellow, Green, Black to Pink, Green, Blue... Audio setup program asks what I plugged into pink, and I selected subwoofer instead of microphone. It says to do so 5.1 surround must be enabled. So I'm assuming that's correct.
If your program has options for the setup you're using, it is probably the correct way or at least one correct way to connect them.
Yes, it's a program installed off the motherboard CD. The MB is capable of supporting up to 5.1 surround...
Well then you shouldn't have a problem, although you might want a second opinion before you use them heavily.
I've been using them for over a month now, and seems to be working. I don't think the center speaker creates any audio, but the subwoofer does, and both fronts.
Well try switching the blue and green connections then and see what happens. I would switch them in the software before physically changing them though.
I just tried to use my headphones by plugging them into the surround speaker, and they didn't work... Guess it's not connected right after all.

Are there any settings in the software for headphones or for the headphone jack on the speaker?
I believe pink is microphone, blue is line in, & green is line out. That's standard on most sound cards.
True, but I didn't know whether the program he has can use the different holes for different purposes.
I would be very hard pressed to image that's a possibility.
Yes, the program allows you to use each individual connection on the jack pack with a custom settings. Useful, but hasn't made troubleshooting this any easier...
I had a problem similar to this with my Playstation's video cables. I ended up needing a different cable so may I suggest trying that?
hi...
i think you go to Logitech website they must have some info related to your problem.
Thanks Andrew Shawn
I've kind of just given up on it. I only use the two speakers anyways and they work just fine along with the subwoofer. There is a connection problem now that causes the subwoofer to cut in and out. Not sure if it's cable related or internal connections.
Surround speakers offer great movies and games to enjoy. Listen to good music, watching movies and TV shows have a closed sound can greatly enhance your satisfaction.
