I have a Razer Blade Pro 17 (Early 2020) running Windows 10 2004.
My laptop panel microphone using Realtek Audio quit working. I attempted to follow Razer documentation to get it working again and then I lost sound from the laptop speakers as well. I performed a system restore to a restore point from a week ago, but still after the 2004 update. Audio and the microphone began working again.
I've been using the system most of the day and hit the Microsoft Store. I had 6 applications that had updates. They installed really quickly (no visible download), and then my microphone stopped working again. Tried to recover to a manual restore point following the restoration where everything was working again, and still no microphone. No packages installed drivers as per Windows logs.
There is definitely something wrong with 2004 and Realtek Audio. The valid drivers are supposed to be delivered via Windows Update, but that hasn't been the answer.
In these days of Covid-19 and remote work, video conferencing is more important than ever. Please fix ASAP!
Thanks.
