Thanks guys, cracked it , had to override the HDMI output in a separate setting with digital!!!
Wow, just got my system up and running, and all i can say is, wow !
bit of a nightmare to start with, was going to get the Monitor Audio BX5.1 with the Yamaha RXV667, then had a last minute change of heart in the shop and got the Denon AVR2311 with the Monitor Audio RX6 AV12, .....
What i did not take into consideration was the fact that i had bought and measured a TV stand for my first choice to the tune of £250 .
When i got home with the bigger gear,,, you got it ,it does not fit in the racks!!!
Oh well, sounds fantastic!!!
