Fix Microphone

Fix Microphone repairs Windows audio input failures affecting voice calls, recording, and dictation. It ensures microphone privacy permissions are enabled system-wide and per-app, sets the correct default recording device, optimizes microphone levels and boost settings, disables aggressive noise suppression that can mute quiet voices, clears audio endpoint cache, and repairs driver registration. It handles built-in laptop mics, USB microphones (Blue Yeti, HyperX, etc.), headset mics, and Bluetooth headset microphones. Takes about 2 minutes with no restart needed.
