so my system is a sonos arc, a gen3 sub and 2 sonos one gen 2.
I had it tuned and it has been running fine for years.
Recently i noticed that the bass seemed to be missing so i played some music and sure enough the sub wasn’t playing anything.
I rebooted everything, my phone, the internet and the system.
Still no joy the app said the sub was connected.
so i disconnected the sub from the system using the app and tried to add it back but the system couldn’t find it so i reset the sub and added it as a new sub and that’s when i lost the existing trueplay tuning.
When i run trueplay tuining it gets to the part where it plays the tones and then says something went wrong. We were unable to custom tune etc.
I have tried to run it on an iphone 14 pro and and iphone 12.
I have also factory reset the entire system.
deleted the app and redownloaded it
And checked system update in the app.
