yeah i have a question about the audio settings. i have it set up through multi channel input into a receiver but the sub doesn't work whenever i listen to music or youtube anything but it does work when i play any 5.1 sources. i don't get why the sub wont work but the center and the other speakers work on non surround sources.it works in the creative labs control panel when i test it. i have the f7 bios install im running windows 8.1 atm but had the same issue on windows 7 i tried both. have the newest creative drivers and everything is setup to 5.1 in the settings. Don't know if im just stuck with it like this or im doing something wrong any help would be great, thanks.
