Managing sound and video settings during Teams meetings and calls for optimal communication
Hello @Natalia Bertowski
Based on my checking, there is currently no available meeting, webinar, or Teams Admin Center setting to disable the sound notification that plays when attendees enter the lobby of a Teams Webinar. Microsoft documentation only provides controls for entry and exit announcements related to dial-in (Audio Conferencing) participants, and these settings do not apply to attendee lobby notifications in webinars.
To help improve the product, I strongly encourage you to submit your feedback directly through the Microsoft Feedback Portal. The Microsoft development teams actively review customer feedback, and many enhancements have been implemented based on community input.
If you decide to submit feedback, please feel free to share the link with me. I would be more than happy to support it, and doing so may also help increase visibility so that other users experiencing the same situation can find and endorse it. The more engagement a request receives, the higher the likelihood that it will be carefully reviewed.
I sincerely hope this feedback will be reviewed and upgraded by Microsoft in the near future.
