Thanks for reaching out and we're sorry for the late response. Could you please tell us what commands do you use when you ask the Google Nest speakers every time you want to play ambient sounds? We'd love to know more about it so we can try some steps that could resolve this.
Looking forward to your response.
Apologies but I didn't quite get what you messaged. For confirmation, has someone sent you an email regarding your concern? If it has a case number kindly post it here for us to check.
A few questions: what Google Nest device do you have and what is the exact command you're giving for your ambient sound?
Keep me posted.
When I got it I could say good night & it would ask what time to set alarm & then after giving a time it would say good night & play country night ambient sounds for 60 minutes. Now it plays all night until I turn off in the morning. Also, when my wife does it, it quit saying good night & playing ambient sounds. It is a Google Home Smart Speaker
