dolby atmos for arc

Good. That’s what you want to see. It means everything is set up correctly and you are getting the best audio that you can get from the Sonos Arc.

For some reason Dolby atmos is greyed out

but I think it’s all set up

that dolby atmos switch is only enabled when using internal speakers, other settings appear to be fine, you should see the atmos logo in the sonos app when playing content with atmos soundtrack from internal apps like Netflix or Disney+. But keep in mind that for having atmos from Netflix you need the UHD plan

Brilliant cheers 

yeah I have the top Netflix package 

can u notice much difference in Dolby atmos?

yes, but I needed to turn up the volume of the height channel in the sonos app, I have it at +3 now. In some scenes there was sounds clearly coming from the ceiling, also the overall sound seems to be more immersive

Oh is it worth me turning up the height volume on mine? 
I didn’t know what that option meant 

Yes, in most cases you should turn the height audio level up. I have mine set to +6. Usually, the higher your ceilings are, the higher the level should be increased.

Is it just trial and error or does the measurements determine how high u need to set it?

You need to find a Dolby Atmos source with distinct height channel audio playing and adjust the height audio level slider until it sounds good to your ears.

Ok nice one

Can’t say I’ve noticed any difference with the height audio
