I have the same issue. It started about 2 weeks ago after an update. Would love to know how to reduce the Google Assistance Volume.

Mine as stopped working as well after an update

i have the same issue, even with the speaker volume off the voice is still loud

Same issue here.

Sonos appears to be aware of it and looking into a fix in the meantime as with Alexa:

Hi Corry P Sonos Staff,

Here the same issue with GA being way too loud. 2 weeks have passed since initial complains and we are still waiting on fixes. Doesn't seem Sonos has there development team on track yet. Hope for the best.

Since we do not know what causes this, we also do not know if it could have been corrected in two weeks or not.

Bizar this isn't still fixed.

Already taking more then 2 weeks for this to be fixed.

It's not like sonos is a small developer with no resources trying to make a fix here. I can understand it might be niche since there isn't enough people complaining about it and therefor QA didn't notice with testing before it got pushed out but this is already taking quite some time rendering my setup in the bedroom useless.

Was lucky I haven't been affected by the app debacle so I think my expectations should be lowered quite a bit seeing the time it takes for that to update :(

GA has always been too loud. But now it’s ridiculous. My first command in the “bedtime” automation is to lower the media volume to level 2. That made it partially tolerable. But now it’s not working at all after the update.  Any hope of Sonos fixing this issue and finally untethering the assistant volume from the general media volume and being able to limit the GA forever?
