Hi ​@maximlequeux 

Welcome to the Sonos Community!

Sorry to hear of this issue you are having with the touch controls on your Amp not working.

There is an option to disable the touch controls in the Sonos app - please ensure that it is not set to Off: Settings » groom with Amp] » Touch Controls » On (dot move to right). If it is already on, please toggle it off and on again.

If that does not fix the issue, please try rebooting the Amp by removing power for a few seconds.

I hope this helps.

Hi ​@Corry P , the first thing I tried was checking that the touch controls were on in the settings. Then I turned it off and on, then I completely reset it. I have also now tried a new Amp with the S1 app, the touch controls don’t work. I changed my whole system to S2 (which means I can now no longer use some of my equipment) and with S2 the Amp’s touch controls work. I can only deduce from that that the S1 app update is causing the issue.

Hi ​@maximlequeux 

OK, I’ll admit that is pretty weird, not to mention conclusive! Just to confirm, you are saying that you tried with a second Amp and saw the same behaviour as with the first?

That is confusing, as I just now downgraded my own Amp to S1, set it up, and I was immediately able to use the touch controls. So, this issue seems limited to your own system so far.

I’ll admit that it has me kind of stumped, however. I was going to suggest a Factory Reset of the Amp until I realised again that there are two Amps behaving the same way.

What I’d like to do now is see what the Amp says. Please adjust the volume using the touch controls on both of the Amps, one after another, then immediately submit a support diagnostic afterwards, letting me know here when you have done so, but please don’t share the number given.

Thanks!

I have the same problem. Resetting does not help. 

Same issue here. After update to the latest s1 app the control buttons stop working on the amp. I checked the setting, turned them off and on again, power reset......no luck.

What did Sonos Support say, when you called them?

If functionality gets lost during update of app, it is likely that the app is not ok. Version 11.15. You can see that many people see the same issue.

You should test it and confirm.that it is a failure and when you expect it to be solved. If I called the helpdesk is irrelevant.

Who is this “you” you speak of?  The person inquiring about you calling Sonos Support is not a Sonos employee, so they cannot confirm anything and aren’t privy to any release schedule. 

Ok, then what is the use of this sonos community if no one is a sonos employee. 

It’s for the community to help each other, even when merely asking if you’ve contacted Sonos Support?

It’s a user community, for users to help each other.  Even still there are some Sonos employees who moderate posts and chime in occasionally.  However, they are clearly marked as “Sonos Staff”, like ​@Corry P who posted above.
