My preamp/av processor does not have HDMI inputs so I am going from my Surface Pro out of displayport to HDMI to the Amazon Basics HDMI Audio Extractor. The 5.1 button is activated and lit up on the device but no matter what I do I cannot get it to play 5.1 to the processor. 2.0 works fine. I've tried both the toslink and SPDIF to my processor. When I run the sub tests in REW it plays out of the L and R speaker. On the front of my processor it says it only recognizing a 2.0 signal. I tried running the 5.1 test in the speaker settings on the EP-HDMI-RX (Intel Display Audio) but when the center, sub or surrounds play I hear nothing - the r and l play fine. Any help would be appreciated.
