I have logitech usb wired headsets and multiple users with dell laptops that constantly have the microphone cut out randomly on them. I noticed that after this happens, that the system files are corrupted. I run a sfc/ scannow after this happens and each time the scan finds corrupted files and repairs them. After rebooting, the microphone works again. Is there a solution that would fix this permanently? I have started using other brands and types of headsets and they do not have this issue.
