📎 AI Summary:
The thread discusses the issue of a notebook automatically disabling its built-in microphone when a headset earphone is plugged in, preventing the use of both together. The original poster asks if this behavior is normal and if there's a way to enable the microphone despite the presence of the headset. A respondent explains that the system typically treats the earphone and microphone as a combined device, and that using different hardware or drivers might affect this behavior. The overall sentiment suggests this is a common hardware or driver limitation rather than a bug.

As you know many (new) notebook have built- in speakers and a built-in microphone.
In addition they offer plugins für a separate headset (with microphone as well).

Now assume the user plugs in only one cable (=the one for listening) of the headset into the notebook
but leave the other cable (=the one for the damaged microphone) out.

The user wants to use the combination headset earphone + notebook microphone.

Unfortunately this seems NOT to work.

As soon as the earphone headset cable is pluged in the notebook microphone is automatically disabled.

Is this correct?

Is there a trick to enable the built-in microphone anyway?

The computer has no way to know that your mic and earphones are both mounted on the same headband. They should be independent. A simple way to check is find some earphones or speakers that you can plug in and see if you get the same problem. The only thing I could see causing that by design is if you are using a headset with its own device driver, and that driver decides that your headset is connected based on the earphone jack.
