So, here is my setup. I am running a Dell XPS 720 desktop with Windows 7 Ultimate SP1 with a Sound Blaster X-Fi Xtreme Gamer PCI Audio Sound Card. Model Number: SB0770
I recently purchased a Logitech Z506 5.1 channel Surround Sound Speaker System. It sounds great with just the subwoofer and the front speakers, but it also has a sound bar and two rear speakers as well that for the the most part, are not being used at all. I use this computer to play games and listen to music, both local music and streaming music from Youtube and Spotify/Pandora etc. Most of those sources as I understand it only utilize 2.0 channels and I want to find a way to get it play over all my speakers. Is there some sort of setting or third party program I can use to make all my sound coming from my computer play through all these speakers?
I also have a separate issue with the sub, but I dont know much about speaker systems. It may be nothing. For anyone who is more knowledgeable than me, the other annoyance I have found is that my subwoofer always seems to be making a a pulsing sound from the speaker. I can feel it pulsing when i touch the cone on the bottom. Its like a tapping sound. If i turn the bass way down, i can barely feel it and barely hear it but it is always there nonetheless. Have tried all kinds of settings from my soundcard.No changes. If i turn the bass down on the subwoofer via the dial it has, the sound diminishes and the pulsing is less strong. I bought it from Bestbuy 2 days ago, so I can return it if anyone thinks it is defective. Any and all help is appreciated. Thank you!
