Microphone setup: set input volume near max¶
The internal microphone works, but not at the default input volume. At the default 51 % it captures almost nothing — measured on this laptop, music playing right next to the machine produced no usable signal. Only after raising the input volume to 100 % did the microphone clearly capture audio:
| macOS input volume | Captured level (RMS / peak) | Verdict |
|---|---|---|
| 51 % (default) | −75 dBFS / −53 dBFS | near-digital-silence |
| 100 % | −42.8 dBFS / −1.8 dBFS | clear signal |
This is a quirk of how AppleALC maps macOS input volume to analog gain on the ALC236 — moderate slider positions behave like a broken microphone.
Setup:
- System Settings → Sound → Input → select Built-in Microphone
- Drag Input volume to 100 % (75 %+ at minimum)
- Speak normally and watch the level meter — the bars should move
- Quick end-to-end check without any extra tools: QuickTime Player → File → New Audio Recording, record a few seconds and play it back
If the level meter stays flat at high volume, that is a real microphone problem — otherwise the capture path is fine and only the gain needed adjusting.
