Hi, I'm on a Dell Vostro 3546 running on Windows 10, 1903. The built-in microphone doesn't work properly, like, when in use it automatically stops recording audio itself.. I've tried almost everything like reinstalling the pc, drivers, checking the privacy settings, everything is fine. The stopped mic, starts working by itself after a while, I know this is weird. To put it straight, the mic only works only when it is in the mood to! Please help me, this causes a lot of frustration while gaming and I can't use apps like voice recorder or perform a voice search on chrome or say something to cortana. Thank you!
