If you're facing the issue of not detecting the mic of your BlackShark V2 X, especially on a laptop, here are some simple steps to fix it:
1. Check the mic mute button. If it's green around the edges, it means it's not muted.
2. Test your headphones on other devices like a phone to rule out hardware issues.
3. If you're on Windows, open the search bar and type "Realtek Audio Console". Once it opens, click on "Device advanced settings" at the bottom left of your screen. After that, under "Connector Retasking" in the "Analog" dialog box, select "Headset (with microphone)" from the drop-down menu. And see if that fixes the problem.
Hope this helps! :)
