This has always been an issue and has never worked since I've gotten the laptop a few months ago. Sound Settings - Playback: Sound Settings - Recording: I can hear audio through the headset, but my computer does not recognize that the headset has a microphone, and instead uses the laptop's internal mic, as seen here.
This whole problem started with me wanting to use my headset's microphone. About my laptop: Dell G3 3579 Signature Edition 圆4 Processor: Intel(R) Core(TM) i5-8300 CPU 2.30 GHz Installed RAM: 8.00 GB Windows 10 Home / Version 1803
