Dolby Atmos not Working Windows 11

Hello,

My setup looks like this: Windows 11 pc (Nvidia rtx 3060 GPU) Sonos beam Gen 2, 2 * Sonos One SL Feintech ax340 Monitor: 27q Omen (does not support eARC)

I have connected everything as instructed with cables that should be ultra high speed 48 GB that suport Dolby Atmos.

While the monitor works well and sound travels to the soundbar when set to 24 bit, 48000khz when I set it to Dolby Atmos for home theater no sound travels. I use the Dolby access app, it says that my sound device is capable of Dolby Atmos for home theater but nothing works...

I don't know if it's helpful but:

1. The sound device shown on my windows pc is the name of the monitor and not the soundbar.
2. The eARC led on the ax340 is blinking and is not constantly lit.
3. In the Dolby Access app when pressing settings I get a screen "Settings are not available for Dolby Atmos for Home Theater"

Thanks in advance for the help!
