I have a USB Microphone K668. After the most recent major windows 10 content update version 1803 (installed on the 5th,), my microphone no longer picks up any audio. Plugging it in brings it up in my device manager, but I cannot get it to show any green bars representing its function. I’ve tested other recording programs and they recognize the microphone as plugged in, but never pick up any sound. I’ve tried uninstalling/reinstalling the drivers from windows to no success. I purchased another microphone, same one, thinking my original was broken. The new one does not work either, in any USB port. I've followed older advice about boosting the levels and unchecking the two exclusive mode options under the advanced tab of the recording subsection. Nothing seems to work. What information do you need from me to help diagnose this issue.
