I just have installed Windows 7 B1 on my machine. I replaced the default sound drivers
from M$ with the ones from NVIDIA and VIA for my board. It is a M3N78 which has (among others) a S/PDIF (or digital) output. I have this connected to a Creative Inspire 5.1. This configuration works quite well under Windows XP. Under Windows 7 I don't hear anything. Any clue how to fix that? In Sound settings or hardware manager there is nothing wrong detected.
