Hey all. I'm very new to computers. I recently bought new speakers for my Vista 64bit operation system. And i can only seem to get 2.1 sound. The speakers that i have are ''Logitech x-530 speakers. I have been doing reacherch on the internet with no problem solved. The one thing i did read was i had to enable and check the 'Speaker Fill' button on Realtek Hd Audio Manager... But i can't find the Speaker Fill option. If anybody could help me achive 5.1 sound it would be greatley appreciated 
Thanks you
