I have a SBLive 5.1 Platnium and I'm having a annoying problem with the input. The thing worked great, but then I put in a new motherboard, and after that, the input won't work. I use the input to pass the sound from my Realmagic DVD decoder to my sound card. If I plug directly into the decoder I get sound, so I know that's not the problem. I made sure the line-in wasn't muted in the volume control planel. I even tried using a enternal cable going from the AUX port of the decoder to the AUX port of the sound card. I've tried moving the sound card to different PCI slot's...uninstalling the driver and re-intsalling it. I'm running Windows ME and my motherboard is a Abit KT7A-RAID. It's weird that the sound card will work fine except for the input...can the input just be shot and the rest work fine?
