I believe this happened after some Windows update. Neither in Firefox, nor in Chrome can I get my microphone to work. The browsers are correctly asking for permission to access the microphone, apparently the website gets a positive feedback, but no audio stream. For example, if I use the online microphone test, the test widget displays a line, but no visualisation of my speaking. https://www.onlinemictest.com/ The webcam works fine, and the microphone does work in other applications. Teams Web even allows me to switch Microphone from my headset to the internal mic, but it doesn’t change anything. Might there be some Windows Policies in play that forbid browsers in general to access the microphone? How can I further analyse this issue? Thanks a bunch already!
