Hi @marinheira 

Thanks for your post! And, apologies for the delay.

Sorry to hear of this issue you are having - we are aware of the problem and are investigating. I’ll update this thread once a solution is in place, but I have no estimate for when that might be.

I hope this helps.

Thank you for the update,  @Corry P   

also, TruePlay is not resulting in a truly improved sound. 
Before these messy updates, the whole system sounded great with Trueplay. Now it lacks treble when compared with the sound with no TruePlay. Tried several times but the results are the same. Tried contacting support, but all they did was to repeat the same advices on support website. Other than that they were clueless and unable to provide any help. 
I honestly hope a future update can also improve true play. 

Hi @marinheira 

I don’t think TruePlay has been altered in any way, so I would not expect it to sound any different than before - except for any differences in the TruePlay Tuning process, of course. Therefore, I see where the agent you spoke to was coming from.

You can try removing your phone from it’s cover, try TruePlaying with a different device, cleaning the microphone, or even just ensuring that your fingers don’t slide over the surface of the phone during the TruePlay Tuning process - all of these things may affect the end result. I do realise this is likely what you’ve already heard, but there’s not much else I can suggest, I’m afraid.

I hope this helps.

Hi again, @Corry P 

The last time I performed TruePlay (yesterday), I did remove the phone case, and I ensured that the microphone holes were totally free from any sort of debris that could impair the whole process. 

Results were about the same.

Are you sure nothing was altered on the Sonos Arc sound profile?

It definitely sounds worse than before. 

Hi @marinheira 

I just double-checked - nothing has been changed with either Arc’s sound profile, nor TruePlay algorithms in general.

Has anything in the room changed? The addition or movement of any furniture, for example? Or, perhaps you are using a different phone than previously?

You could try performing TruePlay while only sitting in the primary seating position for TV viewing, rather than moving around as the app suggests - it should yield different results, though whether they will be an improvement or not is probably subjective.

I hope this helps.

No changes in he room, and the phone is just the same, @Corry P 

I’ll try your suggestion. 

Hi @marinheira 

Understood. Please also note that the elimination of as much background noise as possible is very important for the TruePlay Tuning process.
