Many people have a problem with the microphone (internal and external) automatically muting. Although this problem occurs mostly in Windows 10, the microphone can stop working properly in older Microsoft products as well. Usually, the microphone works fine for a long time, but then it arbitrarily mutes and zeros out.
According to Microsoft experts, this may be due to improper sound settings or outdated device drivers. However, you should not exclude the version of malware/virus infection either. So, if you can’t talk or record anything in Skype because your microphone is automatically and constantly muted, try the following ways.
What causes my microphone to turn off all the time?
When something like this happens, it would obviously be helpful to know the immediate cause. If the microphone keeps dropping despite your attempts to adjust it to a certain volume level, the following are likely causes:
- Incorrect system sound settings.
- Malware has corrupted the sound files.
- The sound drivers have not been updated.
