Hi There, when I am playing music/watching movies on the Sonos App it shows that The Sound is PCM and I cannot seem to change it to Dolby Atmos.

I have the following:

Samsung TV (TU7000 55 TV):

• eARC Active
• Auto
• Dolby Atmos On

Apple TV 4K:
Audio Output - Auto, Dolby Atmos On

Any idea what to do?

Thanks!
