Aukey ep-n5 why audio only in laptop

I just bought new Aukey EP-N5 and found that it can not use as headphone.
I want to use it for conference call therefore I bought it.
My Laptop is Window 10 and Dell Latitude 5490.
May I know that any things to install to fix it?


Hi @ivancy,

Thanks for joining the Community. When you said “can not use as headphone”, do you mean that you can not connect it to your laptop, or there is not voice when it’s connected, or you can not use the mic.
