MBA 15 M3 microphone with closed lid deactivated

[Torty]

A few days ago I picked up a phone call with my MBA which was connected to external display and in clamshell mode. I was surprised I could not be heard.
Later I found out that the internal mic is not working when the laptop is closed. But this worked with my old MBP 2012.

In case this is a question and not a PSA:
This is the intended behaviour.

Hardware microphone disconnect
All Apple silicon–based Mac notebooks and Intel-based Mac notebooks with the Apple T2 Security Chip feature a hardware disconnect that disables the microphone whenever the lid is closed.

Thank you for the link. So it's no bug and there will be no fix.

The microphone on MBA is covered by the screen with lid closed. Even if it's not disconnected, you wouldn't have a good reception anyway.

Today I had the same problem with lid opened. Microphone is working, I tested it via iMessage. 🤔🤔
