Yeah, This happened to me too. I had to make sure I was using a high-speed HDMI cable and then select the monitor as the default device in the old Windows sound control panel. Good luck!
Agreed. I had the same problem. For me, it turned out I needed to manually select the monitor as the Atmos device in the Dolby Access app, not just in Windows sound settings. Let me know if that works.
Yeah, This happened to me with a different Atmos-capable monitor. I had to go into the Sound Control Panel, select the device under "Playback," and manually enable Atmos in the "Spatial sound" tab there.
Can confirm. I had the same problem. Even after that, I needed to make sure the specific app, like Netflix or a game, was set to output Atmos in its own audio settings.
