I made a mistake when I said I was using an AMD 6450. I'm actually using a 6870 in this htpc. I have deleted the realtek audio drivers. I then tried to setup my AMD audio drivers the same as jjd's audio troubleshooting guide. I noticed in the AMD HDMI Output Properties it lists " Max number of channels " as 2. Also there are no encoded formats listed.
Does this mean my graphics card is unable to output HD surround audio?
*edit * Just checked, 6870 apparently has:
"Integrated HD audio controller
Output protected high bit rate 7.1 channel surround sound over HDMI or DisplayPort with no additional cables required
Supports AC-3, AAC, Dolby TrueHD and DTS Master Audio formats"
So it's something else :S
Maybe this: "If formats are missing that you know your hardware is capable of then this points to there being either a driver problem or if using HDMI then it maybe a EDID handshaking problem. " ?
Wtf is an EDID problem :S Should I change HDMI cable?

You have massive GPU and AVR, and both supports bitstreaming DTS-HD/TrueHD audio codecs. With the correct connections and configurations, it should work. Try these-
1. if you enabled CEC in your Denon, try disable it for now.
2. make sure to select the correct HDMI input in Denon for AMD HD6870
3. read my post #2 above carefully, especially the instructions in my post #6
If you did all the above and it still doesn't work, then we can talk about Edid afterward....

It's working now. I think all I did was change my XBMC settings to the ones you posted on the screenshot. After I did that I tried a movie and it was playing normal ( no freezing / jumping ) then when the sound started BAM!
Big smile on my face!! DTS on the receiver screen instead of direct or whatever it was before as proof but I could tell just by listening straight away. tested the opening scene on Saving Private Ryan and some parts of Transformers 1 and it is so good.
I'm sitting here watching different parts of movies I know have loud moments ( action scenes, fights etc ) with a big goofy smile on my face.
I checked the AMD Driver Properties and all the good formats are now listed, just by changing some settings through XBMC. I think I was trying to get it right through windows before even trying too much in XBMC.
One last question. When I play a movie with Dolby it comes up as " Multi " on the Receiver screen and AC3 5.1 on the XBMC Audio list. Is that correct?
