All you are doing, or should be doing, is passing through your audio to your AVR. Your AVR should be doing all the Atmos uncompressing and decoding. If you right click on your audio icon with your AVR on, it should show whatever multichannel you selected such as 7.1. When you hover the mouse over it, you can then get to advanced setup and adjust your audio properties in Windows. When your AVR is off, it should show Stereo. You check this after rebooting once you installed your drivers. Selecting Stereo, 5.1 or 7.1 has no bearing on what your AVR does with it. It's still going to produce Atmos and every other format (almost). Those selections have everything to do with the Windows desktop (like youtube, etc.) and E-AC-3 formats.
You shouldn't update your driver via Windows Device Manager. You do that with the nVidia installer from nvidia.com. You should run DDU Uninstaller. After rebooting you will be using MS generic driver. That's when you run the commands I suggested and delete all the old instances of drivers that will be greyed out because they're not installed or in use. Tick 'show hidden devices'. Be careful what you delete. You don't want to delete anything part of the operating system. Then install what ever nVidia driver package you prefer. I suggest 385.28 unless you use 3D in which there is a better combo of Audio and Video drivers.
OK. I will try that. nVidia only shows the last 4 instances of drivers, but I am sure I can find that old driver on some 3rd party webpage.
The reason I have Atmos for Windows 10 is for Netflix reasons. I agree its more trouble than its worth, but Netflix will not output Atmos unless you have it enabled in Windows 10 through the app store. Secondly, it is not possible to completely delete the Atmos because its linked somehow to my Windows 10 account. I've deleted everything Atmos related on my computer and yet its still trying to be cute by reinstalling it. Its hilarious, Windows will change it DURING a movie being watched. For instance, for 2 minutes voices will be 100% perfect and then bam it cuts out AND the driver has been rolled back.
With regards to the choice of installer, I have tried nvidias clean install standalone more times than you've had hot dinners. Its not the choice of install, its just Windows trying to enable the Atmos package in conjunction with whatever nVidia driver you have. I would bitstream everything to the amp, but Netflix Win10 will only output atmos if it sees it enabled in your spatial sound configuration.
The only workaround is reinstalling Windows 10 from scratch under another new Windows login which is like curing the disease by killing the patient.
While may problem may be news to avsforum apparently, I am not alone in the wider world with people with atmos enabled home theaters. https://forums.geforce.com/default/t...by-atmos-woes/
There is probably just not enough of people like us for Microsoft / nVidia to care enough to allocate resources.
I will try 385.28 as you suggest.
