Yes, and like I said I'm getting Dolby Digital 5.1 received by AVR. However the speaker config is at stereo, if I select 5.1 it says not supported. So windows is putting our stereo channels to the APO, and Dolby Home Theater is upmixing it to Dolby 5.1. I am getting 5.1 at but it's upmixed from a stereo source. When I read about dolby home theater v4 from the dolby website, it says just that, it upmixes stereo to surround. I don't actually want that, I want straight mix dolby 5.1. Is there a better apo I can use that gives me just plain Dolby Digital Live?
I found a post from you indicates to install Dolby Atmos for gaming AND Dolby HomeTheater V4 and mix the two together. I've quoted below. Is that the only method to get dolby 5.1 and speaker config set to 5.1? but just to be clear, I don't really want dolby atmos mixing. I just want a clean dolby digital 5.1 output, and windows aware that the speaker config is 5.1.
Edit:
So I tried your instructions to set up dolby atmos and dolby home theater together. Once again I can select Dolby Digital in advanced, and I get Dolby Digital 5.1 received by my AVR. However I still can't select 5.1 under speaker config if I have Dolby Digital selected in advanced. (I can select 5.1 fine if I have PCM selected in advanced.)
Also when I start dolby atmos for gaming, I get error there is a problem accessing the driver.
