Report "Motherboard fih57 since a few weeks after downloading newest nvidia drivers, I can't get the on board realtek chip or software do deliver dolby or dolby dts via my spdif optical anymore to my receiver. It's not the receiver. I have tested it with other machines. I also have a new panasonic flatscreen with wifi but not on the ethernetwork. It looks like something has affected the realtek chip or software. Can you help because I do not want to load drivers for a chip that was set up by Packard bell"
