how to turn off mute notification

did you get a reply to this?

Hello,

This may have something to do with your accessibility settings and screen reader alerts.

"Screen reader alerts allow you to hear custom announcements using your screen reader whenever specific actions are performed in Zoom, such as when the host has muted audio, when closed captioning is available, or when you have received an IM chat message. You can manage which alerts you want the screen reader to announce."

In my case, this behavior turned to be the fault of my Plantronics Blackwire 5220 series USB headset. You can customize headset behavior using Plantronics Hub Desktop, https://www.poly.com/us/en/support/downloads-apps/hub-desktop . The options are "Voice", "Single Tone" and "Double Tone". Unfortunately, Plantronics Hub does not offer a way to turn mute notification off entirely. (The beeps are better than the voice, but they are still unpleasantly loud...who comes up with terrible features like this?)

Unchecking the "sync buttons on headset" option (and restarting Zoom, which is necessary for this setting to take effect) does avoid the beeps, but makes it possible to have an inconsistency between the headset buttons and the Zoom mute status.
