Hangouts Meet and Hangouts Chat were rebranded to Google Meet and Google Chat in April 2020.
If you are still having trouble with your microphone, here are is another solution to try: Check your app permissions In order to provide enterprise-grade online video conferencing to everyone, we announced a free version of Google Meet in May 2020. It is likely that there is a problem with the webcam driver that is making the Windows 10 camera not work.
I have an Inspiron 13-7352 and am running Windows 10. Even now, I can use Google Hangouts, Skype etc with no problems (as of Thursday 6th August 2014 2150). However, I cannot search Google Chrome or use any voice dictation software by voice as my microphone is 'not recognised', which is clearly not the case, as I was able to use it successfully less than 5 minutes ago. The apps for checking the sound may not work when Google Hangouts is running. This is great because Chrome has recently been crashing whenever I try to open it with Vivaldi open, and hangouts has been doing the same thing. Available on mobile or on desktop, start making video or voice calls today. My microphone doesn't seem to work for any applications. We announced in 2019 that we would be migrating all classic Hangouts users to the new Meet and Chat products. Google Hangouts is a great place to hang out and chat with your friends, family, and coworkers.
