My Dell Inspiron 7353 2-in-1 has 1 audio jack located on the side. It has a picture of a headset next to it so I believe it's a TRRS type jack. Whenever I connect headphones(with a mic) to the audio jack, my computer picks up the mic but doesn't use it. Whenever I'm on a call with another person they can hear me fine with the mic set to "Internal Microphone (Conexant SmartAudio HD)". But whenever I switch to "External Microphone (Conexant SmartAudio HD)" (this is my headphone mic) the other end can't hear me at all. I used the same headphones on my other computer and my PS4 and the mic on my headphones worked fine. Please help me solve this issue with my mic. Thanks!
