Hi I have Windows 10 and Nvidia GTX 650 driver that's connected to a 5.1 Receiver with HDMI cable. I can't get 5.1 sound out of my speakers when I play music on iTune, or watch Youtube (but VLC Player works). I understand that the sources are stereo but either Nvidia GTX 650 or Windows 7 would upmix it before.

Can someone help? Thanks.
