pub fn find_by_id(id: &str) -> Option<MicrophoneDevice>Expand description
Locate the MicrophoneDevice whose stable id matches id by
re-probing the OS via list_microphones. Used by callers (the
app crate’s start_mic_capture) to resolve the picker’s mic id
back to its native gst device-uid on every session start (M-MIC.3
/ AUT-284). Returns None when the mic was unplugged between
enumeration and start.
