Hi Robert,
Since the microphone works in other apps and the same issue occurs on two Android devices, could you please sign in with the same account at Copilot on the web and check whether voice works there? This will help determine whether the issue is limited to the Android app. Also, please share the Copilot app version and Android version installed on both devices.
If voice remains unresponsive after the troubleshooting steps already provided, please use Profile/Menu > Give feedback or Send feedback > Report a problem and include the device models, app version, Android version, and a screenshot of the inactive waveform. This information will help the Copilot team investigate the issue.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. My role is limited to providing technical guidance on reported issues, requests, or ideas. Thank you so much for your understanding.
