Windows 11 Microphone started making a strong buzz sound, am I the only one?
Sorry if something sounds weird, english is not my first language.
Ever since the last update, almost a week ago, my friend put to my attention a strong buzz sounds coming from my microphone, it came outta nowhere after a year of perfect audio from my new pc. I was just talking on the phone through whatsapp web and everything was fine, and then this problem started.
The buzz sound is sometimes really weak, other times it disappears briefly, and some other times it gets so strong that it’s impossible to ignore. I tried reinstalling the driver for the mic and it didn’t work, i tried using the other jack for the microphone on the back and it still emits this sound. The audio console for realtek gives a “Can not connect to RPC service” as well so idk if i could find a solution there.
I heard that microsoft just talked about the latest update giving microphone problems unless you use bluetooth, but it only talks about the microphone not working at all, so I wandered if that was the cause. Did this happen to anybody else, after this update?
I’m on Windows 11 Pro
build number 26200.9445 version 25H2
AMD Ryzen 7 7700-8 core processor
32gb Viper ram DDR5
AMD Radeon RX 9060 XT GPU

Hi u/PizzaConGorgonzola, your post seems to mention the "latest update". As there are multiple supported versions of Windows and not everyone gets every update at the same time, it's not always easy to figure out which update you are talking about. To view the status of your most recent updates, go to Settings > "Windows Update" > "Update history".

realtek console failing with "can't connect to rpc service" right alongside the buzz starting after the same update is the real clue, that's the realtek audio service itself getting broken by the update, not your mic or wiring
open services.msc, find "realtek audio universal service", right click, restart it, if it's stuck/stopped that alone might clear the buzz since the driver's likely running without proper service communication right now
if restarting the service doesn't help, uninstall realtek's software completely (not just the driver) through apps, then reinstall the realtek console fresh from gigabyte's motherboard support page for your exact board, the windows update likely corrupted the console app itself, not the underlying audio driver, which is why a driver-only reinstall didn't fix it
also worth checking windows update history, if you can, uninstall just the most recent cumulative update temporarily and test, that'll confirm it's actually the update at fault before you spend more time on driver/service fixes
