Hope that you are wellJ
Connecting the speakers correctly seems to be the biggest issue.
Try this diagram: http://logitech-en-amr.custhelp.com/cgi-bin/logitech_en_amr.cfg/php/enduser/std_adp.php?p_faqid=2913&p_created=1125714076&p_sid=gel419fj&p_accessibility=0&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9OCw4JnBfcHJvZHM9ODQ0LDE3LDY0MCZwX2NhdHM9JnBfcHY9My42NDAmcF9jdj0mcF9wYWdlPTEmcF9zZWFyY2hfdGV4dD1OTyBTT1VORA**&p_li=&p_topview=1
Be sure that you are not set to stereo
You must have at least a 6 channel card.
After verifying that the connections are made correctly, the sound card needs to be checked to make sure it is setup correctly. There are many sound card manufacturers so we cannot possibly cover every make and model. We recommend contacting the manufacturer of the sound card to make sure the sound card is setup correctly for use with analog 5.1 speaker systems.
When a software DVD player is being used to watch a DVD, the audio output needs to be set to surround sound mode. Please refer to the user manual for the software DVD player to check the settings.
Many DVDs have more than 1 sound
format available. Just as the sound
card and the software DVD player, the DVD itself has to be set to the correct sound
Finally you can test to see if the speakers are working correctly by plugging the front channel cable coming from the sound card to the rear channel connector on the subwoofer. If sound comes out of the rear speakers, then there is no problem with the speakers. The problem could be with the software DVD player, or the audio setting on the DVD.
If I can be of further assistance, please let me know.
And, remember; always include the type of Operating System and the type of computer you own, when you submit your questions.
It simply makes for much faster solutions.
Have a wonderful morning.
