Built-in Microphone Stops Working with No Input Signal After Updating to macOS 26.0.1 (Tahoe)

Hey all, I updated my MacBook Air M1 to macOS 26.0.1 (Tahoe), the built-in microphone stopped working. The input meter in System Settings → Sound → Input shows no signal at all. External mics work just fine, with signal showing. The issue persists across all apps, including Voice Memos, FaceTime, and third-party recording software.

Anyone shares the same problem?
