i want to disable mic of participants for a conference call.
The microphone cannot be disabled but… you may default your users to “Start with audio muted”.
Jitsi Meet SDK for Android contains a WelcomePage React Component which renders at the top left a hamburger menu, which in turn allows access to Settings where there’s a toggle “Start with audio muted”. The toggle is backed by persistent state so I imagine a forked Jitsi Meet SDK for Android may default the toggle to true.
Additionally and alternatively to forking Jitsi Meet SDK for Android to change a default, when you’re passing the meeting URL from your app to JitsiMeetView#loadURLObject you can add the config/configOverwrite/configOverride startWithAudioMuted=true.
