Will this system sound good. sub woofer help?

Sub Woofer will not work with my Playstation 3. Help!?

• I just got a Sony STR-DG720 7.1 channel receiver. I also just got a Insignia-5.1-Channel Home Theater Speaker System. This is my first surround setup Ive ever had so im not so sure how to use it. I hooked everything up, the speakers to the receiver and the sub woofer to the receiver. I Hooked my Time Warner HD Cable Box up by HDMI to the Receiver and My Playstation 3 by HDMI to the receiver. The receiver is connected through HDMI to my TV. Tv sounds great, all of the speakers work and the sub woofer is very powerful. When I use the Playstation 3 however i get perfect sound from all of the speakers but the sub woofer does not function at all. Somebody please help me out. Thanks

• Answer:

  You need to connect your PS3 to a receiver where the speakers and subwoofer is connected. You cannot connect the speakers/subwoofer directly to the PS3. The PS3 comes with an optical audio connection which is required if you want to get surround sound (and thumping bass) from your PS3. It is possible to get surround systems for about $150-200, but I can't really say they're that good... Just be sure the system you get comes with a RECEIVER - not one of those cheap DVD players with the speakers directly attached to it. Those don't have any additional inputs.
