No more sound...

Up until a few minutes ago, I had sound going through my reciever to my speakers. I have an X-Fi Platinum hooked up via the front coaxial spdif to my sony HT-6600DP reciever (the coax slot for the dvd in the back). I've been using it and it's been working great (except I rarely hear the surround speakers working) up until a few minutes ago when the lcd panel on the front of the reciever stopped showing any sound hookups (usually it has R, C, L, SR, SL, & SW lit up). I know my reciever didn't die because I can still listen to the radio on it. I know most of my settings are still good because I can hook up my headphones to the x-fi panel and they work fine. So, somewhere in-between the computer and the reciever, there's a problem. However, I have no idea what it could be. I even tried a bunch of different RCA cables and none of the worked.
Somebody plz help me!

Try repairing it with the sound cards cd that comes with it. I have an Xf-i and every now and then when I install new programs it doesn't work, and repairing it makes it run like new again. That happens due to some programs or other drivers having conflicts with other softwares like the sound cards driver. So repairing it should do the trick.

If not then it's should be a problem of your connection. If you're using recievers then hook it up to the right place and switch the connection setting from analog to digital.
