Question No 5.1 audio getting to my Receiver via HDMI to TV as PC sees the TV has only 2 speakers

Hi, 1st time here,
I found an answer here for one of my PC to Receiver problems in the forum so I thought I would join up and ask about the other
I get no 5.1 audio to my Receiver as the PC see the TV only has Stereo speakers, how do I get it to allow the 5.1 channel sound through to the Receiver
If I trial the Dolby Access for Headphones it place perfect 5.1 channel sound, although I was looking forward to watching more than their samples
(my DVD player hooked up via HDMI same as the PC send 5.1 straight through)

How is everything connected and what are the models of everything you are connecting? Without knowing what you are using no way to know how it should be wired.
