I just bought the Logitech X-530's but I can't get the rear speakers to work, I have a 5.1 sound card and all the cables seem to be plugged in correctly. Any suggestions on what I am doing wrong?
Thanks,
John
 
check the manual first. My Altec Lansing speakers require you press the mode button to turn the rear speakers on and off. If you can't find anything there, first make sure the cables are in right, as colors might not match. Then swap rear and front channels and see if the sound moves like it should

Remember just because you have surround channels doesn't mean sound will come out of them. Most systems will only play stereo sound over the front two speakers, as that is what 2 channel sound is. You need to test it with either a 5.1 source or by some emulator that will derive the rear channels such as Dolby ProLogic
 
i hade same probleme , it was because it was not properly configured with my sound card , check that first
 
Yah, a program called PCI Audio Apllications, It's divided into Audio Rack, CD Player, MIDI Player, Mixer, and MP3 Player. Which one do you think it would be under?
 
I dont really know, just check all of those and see where you can configure what type of speakers you have. If it is a decent sound card, there should be a 5.1 selection.
 
go into mixer and see. Also go into control panel---->Sounds and Audio Devices and hit advanced set up. Make sure you have 5.1 speakers selected
 
To complicate the issue more, listening to the speakers more carefully, only the front speakers and the bass work. The rear speakers and the center speaker are not working. This doesn't make sense at all to me, the bass and the center are on the same plug and only one off them work? When I test them individually, (putting one plug into the sound card at a time) the bass works without it being plugged into the computer! I can fell the bassline on the bass speaker even when the bass/center isn't plugged into the sound card. Does this make sense?

edit:
Also, the bass doesn't work unless the front speakers are plugged in, which doesn't make sense either because they are different plugs into the sound card.

it's because the speakers use an LFE crossover. It actually feeds the L/R channel to both the sub and the L/R speakers, but it uses a high pass and a low pass filter to make sure only the sub plays the notes below a certain frequency and the main speakers play the frequencies above a certain frequency.

This is really common with computer speakers, as it lets someone without a card that has discrete LFE output to use the speakers and still get bass. When you hook up a source that has discrete LFE, then it's just added into the mix. You don't notice it as a card that seperates sound into 5.1 will already strip out those frequencies and send them through the LFE cable.

Double and tripple check your config, it sounds like your card set up for 2 channel stereo and not 5.1
