My microphone sound is randomly not picked up by Discord

I have a problem since the last update.

When I'm talking, the sound of my microphone is randomly hashed. Because of this my sentences are totally ununderstandables by my friends.

I tried everything in my microphone settings in Discord, even reinstalling Discord itself : nothing worked. The problem is the same in the web version of Discord. In other apps my microphone works perfectly fine, so I'm sure that my problem is from Discord.
