Hey guys, I'm currently using the onboard sound from my Gigabyte P35-DS3L board. I have the Logitech Z-680 5.1 speakers. I can't seem to get surround sound from streaming sites such as YouTube. When I had my Audigy Card this wasn't a problem. Some movies in Windows Media Player don't seem to work in surround sound either. I have made sure windows know it has 5.1 speakers in the control panel>audio section. Is there some codec I'm missing or something? All help is appreciated. Thanks.
