First, download Realtek Audio Console. You can get it for Dell by following this link.
Next, make sure you have the Realtek Audio Service running (if you need to, do a fresh install of Realtek Audio Drivers — you can get them here).
Now, make sure you have the Realtek Audio drivers and services running and open up Realtek Audio Console. If you don’t have the drivers and services necessary for it running, it won’t start, so if that happens, bring up services.msc from a command prompt and, as I said, turn on the Realtek Audio services and drivers.
Plug in your headset. If prompted, choose “Headset with microphone” as the device you pluggeed in. If it only gives you “Headphones” for now, just go with that. It may keep spamming the message at you; just hit “OK” once. It will stop spamming you shortly, and after you close the console.
Click “Headphones” in the Realtek Audio Console, or “Headset”, if it gives you that. On the bottom left, you should see: “Device advanced settings”. Click it.
Slide “Enable jack detection” to on. Below, you should see the “Connector Retasking” heading; below that, you should see, next to a picture and the phrase “Analog jack”, “Headphones”. Change it to “Headset with microphone”.
Now if you want to change microphone settings, in the left pane, choose “Jack Mic”. That’s now your headset mic.
Hope this works for you. Took me way too long to get a stupid Razer Blackshark X V2 working on my PC.
