Thank you for a fast reply and sorry for not specifying the apps I tried.
I apologise if the issue is not completely Microsoft related but due to the number of applications affected and a reset causing the issue I thought it may be the case. I folllowed the steps in this video however nothing seems to work.
I performed some more tests. To check if a microphone is working in browser I used webcammictest.com/check-microphone.html and speakpipe.com/voice-recorder. These sites seems to work fine on other browsers I tested. I made sure to enable microphone access
on those sites.
My microphone doesn't work on the following apps:
- Google Chrome: Version 80.0.3987.132 (only using uBlock Origin, I doubt it's the issue)
- Opera Version: 67.0.3575.53 (fresh install)
- Discord Stable: 55865 (4f90d73)
However it works perfectly fine on Microsoft Edge, Mozilla Firefox, Skype and Windows Voice Recorder
Furthermore, after some digging I found that it may have to do something with a format. The following applies to all affected applications:
- Using 2 channel, 16 bit 48000Hz (DVD Quality) I hear a quiet noise while I'm not speaking and it goes completely silent when I make a sound.
- Using 2 channel, 16 bit 44100Hz (CDQuality) I can barely hear a sound when I make one. It's very quiet but not completely silent.
I don't have any more format options (Sound -> Microphone Properties -> Advanced).
