Proposal

Meeting Assistant currently records the Windows default microphone endpoint and offers no in-app way to choose a different input. Users with multiple microphones need a stable configuration default and a quick tray-menu override without changing Windows settings.

Changes

• Add an optional Recording:MicrophoneDeviceId setting.
• Keep using the Windows default capture endpoint when the setting is blank or absent.
• Enumerate active microphone capture endpoints for the tray icon menu.
• Add a Microphone submenu to the tray icon menu with one checked item for the effective microphone.
• Let selecting a microphone from the tray menu change the microphone used for the next capture start.

Impact

• Affects Windows audio capture setup and tray menu rendering.
• Does not change system loopback capture or transcription provider behavior.
