Dolby Atmos doesn't work on RX 5600 XT on Windows 10 via Optical HDMI 2.1 connected to LG C1 Atmos TV. Fix your audio driver. System shows option (support) for Dolby Atmos Home theater and it keep switching to stereo no matter what you do. Sound from tv is basicly trash with your driver. I have Xbox Series X and Atmos works perfectly fine on this TV, so it's your graphic card. I don't care about some third-party APO driver which was told as a solution on this forum. FIX YOUR AUDIO DRIVER. THIS THING WORKS EVEN ON APU. ARE YOU SERIOUS?
