Question Pc wont detect multiple audio output

[abid.dk2]

Hello,
I got a speaker and headphone. One day my friend come to my room and watch me play pubg, he want to hear what my teammate are talking about, but i need to use headphones to know where i got shoot from, so i tried to plug my headphone to the mobo 3,5mm jack and speaker to the front panel 3,5mm jack, but windows only recognize one of them(speaker only or headphone only). How to make windows recognize both of them, so i can play using headphone while my friend are able to hear and enjoy the game too. Thanks

Headphone and speaker both use 3,5mm jack, and i got msi b450 board, the front panel audio is plugged to the internal io

Your motherboard audio options may have the ability not to disable speakers when headphones are connected. If not, you can get an audio mixer or splitter cable and connect the devices to that.
