Thanks for your reply,
I thought about using hdmi extractor,
Before I purchase this item my question is if the computer will recognize the hdmi connection with 5.1 channels from the receiver or 2 channels from the TV.
i have connected my computer (Intel nuc) to my Tv (Hisense 55" model LTDN55K390XWAU3D) throgh HDMI cable.
since my reciver (Sony STR-DG500) doesn't have HDMI input, i've connected optic cable from th TV to the reciver.
i want to get 5.1 surround sound, but it seems the the computer recognize...
