Solved Problem with Audio Driver Not Reading My Speakers. (rear input)

[yupp8]

I did not know where else to post this, since my sound card is on my motherboard and i have amd processor i tought it might be the right place.

I own MA770 - UD3 motherboard.
Yesterday my speakers worked just fine and i had speakers connected and a USB headphones, and i could switch between them.
today i plugged my speakers out and after it I plugged them back in, something must have went wrong with my driver , look what's happening -
Audio problem. - YouTube
that's the video that i made to describe my problem.
if i try to connect them to my front input it works just fine...
what the hell ??

problem solved, updated the driver, windows told me i have the latest version but i went straight to realtek website and downloaded The latest Realtek HD Audio Manager.
works like a charm.
