So my issue is that my Sager laptop came preinstalled with Realtek High Definition Audio manager. This manager is the problem, as it won't allow me differentiate between the headset microphone and the internal microphone. So while playing games like No Man's Sky, even if I mute my headset's microphone(with a switch beside the volume), my laptop's internal microphone still picks up my voice... In device manager, there's no separation of my headset and internal mics, but rather Microphone(Realtek High Definition Audio) as the only audio input device, and in the software for Realtek HD Audio, there are no options to correct this. Can anyone help me disable my laptops internal mic, while allowing my headset mic to work?
