How to re-enable a microphone in Windows 7

In the last few months, I have twice had a situation whilst using web conferencing, where the computer has got confused with the internal microphone and the headset microphone – and the only way for me to solve it was to disable the internal microphone. The only problem with this, was once disabled, I couldn’t then find the option to re-enable it afterwards.

After much detailed and systematic searching (discovered by accident after randomly pressing and clicking) I found the solution.

Which I will share here in case anyone else has the same problem.

  1. Go to the control panel
  2. In the search box, type ‘Audio’
  3. Under the heading ‘Troubleshooting’ there should be an option to ‘find and fix audio recording problems’ which should then re-enable the disabled microphone.
Control panel, search for Audio, go to Troubleshooting
