stupid middle speaker wont work

[NewCents05]

i bought logitech x530 speakers really cheap on ebay and after like a lot of searching finally found the game adapter so you can connect the speakers to a tv. i made sure everything was connected right but the middle speaker thats like sideways and different from the rest doesnt work. It works if i connect it to a pc but not the tv. Any ideas how to fix this.

ur output must be coded in 5.1 to get a real surround sound out of all speakers. If its just stereo sound, ul hear it in 4 speakers, the 2 back being duplicated from the 2 front.

wtf does that mean. the game adapter is this http://www.logitech.com/index.cfm/products/details/US/EN,CRID=2177,CONTENTID=10036

it has the 3 thing orange green and black and connects to the left and right audio thing on the monitor output in the back of the tv.

put a dvd in ur player, and make shur u got surround sound selected in the options, and tell me if u hear sound from all speakers. And reread my 1st post, i think its comprehensible...

oooo ok yea i reread ur first post and it was in something called effects on the tv. I had it on simulated which shut off the middle speaker and the subwoofer dont know i didnt realize that. sounds way better with nthe effect off and the middle speaker works. Thanks
