I'm currently using my onboard sound provided by the Gigabyte P35-DS3L board. I have the Logitech Z-680 5.1 speakers. My problem is that when using Windows Media Player or Winamp my computer utilizes all 5 speakers. But when using streaming sites such a Youtube it only used the Front Left, Front Right and Center speaker. Does anyone know how to set it up so that I can utilize all 5 speakers? My old computer which had a Audigy card seemed to have no problem utilizing all the speakers.
