3.5mm mic: how to explain my MacBook that it's just a mic and not an headphone set

Like title, I'm using a Boya M1 lavalier mic with a 3.5 mm plug. When I put it into the jack (that is the same of the headphones), my audio go mute, because computer thinks I'm using a headphone. Luckily, the mic works as expected, but I can not hear any audio. So if I am in a conference, I cannot hear them.

Is there is a software solution? If not, what hardware solution could I use?


Solution 1:

You do not have a microphone jack. You plugged your microphone in the headphone jack. This is why you can not select internal speakers.

Try one of these adaptors:

USB Type A:

USB Type C:

Or get a USB microphone and skip the adaptor.

Perhaps the jack is for a headset (combination microphone/headphone).

There is this question: How to use a wired headphone AND a mic at the same time on the Macbook Pro Retina?. The answer would suggest the jack would accept a plug with two rings. This would allow the jack to be used for a mono microphone and stereo headphones. If this is your arrangement, then the you still would need a USB solution since using the jack would not allow the internal speakers to be used.

Although, you have to wonder. If you used the microphone jack and left the headphone jack unused of an adaptor, like the one shown below, then could the internal speakers be accessed? My guess is probably not.
