I have a Dell Inspiron 15 5000 gaming, it has a combo audio jack and I am trying to get it to see my headset which has a builtin mic which uses the 3.5mm. so far the system only recognizes it as headphones with no mic. there is only the internal laptop mic showing up in the recording tab under the sound settings. the headset works fine for listening but the mic is not working. the device manager detect my headset as "headphones(high definition audio device)", which I believe to be the problem (if i am understanding the difference between headset and headphones correctly: headphones do not have a mic, headsets do)
