Windows 10: Microphone Muted

Hello,
When I use Camera to make a video on my Lenovo, a window appears with a error code: 0xA00F429D<MicrophoneMuted>. Videos created have no sound. I've got 18 machines and two of them have the same problem.
I checked the access of the camera to the microphone and the system tells me everything is ok... And all the volumes are ok.
Thanks for your help.

 

microphone mutes itself


When i go into properties the mike is muted. When I unmute it works for less than a minute then mutes again. The only suggestion I have found is set as default device which does not solve problem. I have also read it is a virus but I cannot solve with malware or virus scans. It first became a problem just a few weeks ago while skyping. Never had a problem with mike until then.

Troubleshooter finds the microphone muted and fixes, Within a minute the microphone mutes itself again.

 

muting microphone


Same issue. Windows 10 mutes the microphone only for Google Hangouts.
I found it muted when I go to Sounds and I unmute but still doesn't work.

Troubleshooted from the sound icon and the mute issue didn't even come up as an issue.

Searched on microphone in search and then troubleshooted it from there (the troubleshooting looked different from there) and it came up that the microphone had been muted and was fixed. And guess what? I could use my microphone again.

I have found it will just mute itself again for no reason that I can find out.
