I just noticed that the sound on my system seemed funny. I checked the creative X-Fi panel and had it identify the sound channels. I found that the front left worked fine, but the center channel was coming through the center and front right speaker and the rear channels were coming through their respective front speakers. Has anyone had this problem before? I don't know when it started because I just noticed it by accident.

thanks

What version of Windows are you using?

Do you have a sound card?
If so, what is its make/model?

He said that he is using a SB X-fi... Obviously that is his sound card.....

My tips:

Disable all other sound devices (onboard, etc)
Uninstall//Reinstall Drivers
Check all connections with speakers....
Then enable 5.1 mode

Good Luck! I don't know what else to offer!
