I connected a microphone with a jack connector to my laptop (Lenovo only has 1 jack connector), but it is only recognized as headphones.
You need a 2 jack to 1 jack adapter. Available on Amazon.
Must have 2 sockets that run on 1 jack
A Y-adapter from two 3-pin to one 4-pin.
It still doesn't work even with that
Now it works, thanks
