I think I posted my original thread in the wrong forum location.

It looks like the current 5.1 speaker configuration is not set to the Dolby spec and game audio is not positioning correctly as a result.

I would love some feedback from RME on this as it's meaning that my audio team cannot update their driver software beyond v1099, which is a couple of years out of date.

Thanks
