Dolby Atmos sound option is missing all of a sudden

Hi
I run my PC to my TV via an HDMI cord from my 3080ti my soundbar is connected to my tv on a seperate HDMI port , everything worked fine for about 2 years.I just checked my sound settings and noticed Atmos was not enabled so I went to enable it and the only thing in the drop down is sonic for headphones.
I do not care about Atmos for headphones but I need Atmos for Home Theater.
My TV appears in sound devices as normal

I Used DDU to uninstall both the Nvidia Driver and the Realtek sound driver

Reinstalled 2 versions of Nvidia drivers and no good
Removed realtek audio through DDU no luck with Atmos
Did this several times and no go.

How do I get the Atmos option back? สมัครเดิมพันบาคาร่าเว็บตรง

I have Dolby Access but it is not subbed to but it says it only needs a subscription for Headphone use.
