I am having some issues with my sound configuration. Firstly, I am running Windows 7, and I am using the beta driver that creative provided for windows 7. I have a Philips DVD home theater system hts3544/37 running in digital in mode. The X-Fi Surround 5.1 device is using an optical cable that is running into a optical in to digital coaxial out converter to my home theater system. The problem is when I go into my speaker configuration settings and choose 5.1 Surround,the speakers and only get sound from the left and right speakers. There was one configuration that produced faux sound, it played a sound for each speaker, but the sound seemed to be coming from the center speaker only. Any help would be greatly appreciated.
