I'm a recent purchaser of Sonos products, after being impressed with them in holiday rentals.
My first purchase has been the below:
Arc
Era 100 x 2
Sub Gen4
The interesting, not to mention frustrating, thing I've found is the fact Trueplay is missing from the Arc settings.
The Era 100s both show the option to run Trueplay (when not paired as Surrounds with the Arc) but the Arc is completely missing it even when not paired with any other speaker.
I've tried the below to rectify this, based on other posts and videos:
Rebooted all speakers - issue is still present
Unpaired everything, including the sub - issue is still present
Reset the App - issue is still present
Cleared all App cache and data - issue is still present
Cleared all App cache and data, then uninstalled and reinstalled the App - issue is still present
Paired the Eras back to the Arc - issue is still present but now I obviously cannot Trueplay the Eras as they are in the Arc 'system'
I'm using a Samsung S21, I've seen lots of reports of Trueplay not being present on Androids but the fact it is present for me for the Era 100s, says something different.
I've added a couple of screenshots, one of the Arc settings and one of the Era100 settings.
Can anyone point me to any more helpful info please?
