So ever since I got the Inspiron 15 7567, the external microphone with my headset is not detected. This is the same problem I had with my previous laptop, the Inspiron 13 7000, but it was a simple fix with just the changing of a few settings in Dell audio. However, when I attempted to do the same on the 7567 I could not find Dell audio. I've checked the toolbar, control panel and when I search Dell audio in my pc it comes up with nothing, despite this the Dell website says that all my drivers and systems are up to date. Anyone think they can help me out on how to fix this?
