UPDATE: So for no reason at all i was just messing around and decided to plug in a Type C to 3.5 mm jack connector on my laptop. I connected my headphones through that and VOILA! somehow it all works. my laptop is registering the mic on my headset too. I dont know why it works, but it works.
I bought a Dell G15 5520 less than a year ago, I have recently noticed that whenever I have to use mic my laptop uses the inbuilt microphone array (intel smart sound technology for digital microphones). My headset is a Razer Kraken X Superlight. This laptop is a Windows 11, 64-bit operating systemWhenever I plug it in i get audio from applications but the laptop does not use the mic from the headset.  I am fairly technical and so I have tried every possible method- running the audio troubleshooter, switching to headset with mic from realtek audio console, updating drivers, uninstalling and reinstalling drivers, giving microphone access to apps etc. None of them seem to work.  However i know that the headset mic works just fine as I tested it out on the HP Omen that i have. Below attached is a screenshot for the audio manager and what it looks like when i open them. [IMAGE] [IMAGE]   As you can see the Jack Mic says it is ready however doesn't seem to have any sound activity being picked up. Even in the realtek audio console I have it set to Headset with microphone and it still doesnt use the headset mic. I should state that even though the "enable auto popup dialog, when device has been plugged in" is set to "On" i never receive any such popups. I would really appreciate some help on this.
