If your headset microphone isn't working on Debian 12, you can try several steps to diagnose and fix the problem. Here’s a checklist of things you can try:
### 1. Check Physical Connections
- Ensure that your headset is properly plugged in. If it's a USB headset, ensure that it's fully inserted.
- If your headset uses a 3.5mm jack, make sure it's connected to the correct audio port (often color-coded, pink is typically for microphones).
