PC stopped working with dolby atmos after power failure

So my PC is connected to a UPS, and when i go to bed i put it in hibernate, there was a power failure at midnight and the UPS made lots of noise so i disabled it
When i woke to use the PC i noticed speakers werent working, i change the atmos setting to stereo and they are working, enabling atmos still not working

I got the latest nvidia driver, reset settings and its still not working, rebooted a few times but no go

I am using an RTX 3080 connected to TV and Earc through receiver, my Nvidia Shield is working fine as i played an atmos movie and no issues

When i set PC to atmos, the volume bar in control panel is moving when i am playing youtube but nothing comes from speakers, i click format and choose 24 bit and speakers work, change it to atmos again and silence

I have all the windows patches, all MSI drivers and latest nvidia drivers

How would i fix it?

Thanks
