I have a Samsung sound bar that supports Dolby Atmos and DTS:X, but it is not recongized by windows or is being blocked by the driver. Maybe it is an active surround signal it needs to switch to Atmos or DTS:X, I don't know much about it. One thing I do know is my soundbar does switch to Atmos using the TV and my Sony Blu-ray player, but not my PC. I have tried all different kinds of setups and the best I can get is the PC recognizes it as supporting Dolby formats (about 7 different types), but not as supporting Atmos or DTS:X. Any help would be appriciated. Thanks
