Windows 7 – Enable, Disable, and Switch Between Internal and External Microphones

audiomicrophonewindows 7

Im Windows 7, I use a Headset microphone to dictate to the computer. I was not sure at one point if the internal microphone was disabled or not and thought that maybe it was used instead of the headset microphone. I have tried to find a way to check this and search under Sound/Recording. There were two microphones there. I have identified the external one by the fact that if not connected the message 'not plugged in' appeared.

I have selected Properties and selected to disable it

Now a single (external) microphone is present under sound and there's no obvious setting there to re-enable it.

I went to Device manager and found two devices there, both displaying only the 'Disable' option.

I want to know how to enable the internal microphone and also what is the proper management of microphones for the purpose presented above.

The first part of the question - related to re-enabling the disabled microphone was answered here.

So, I have a partial answer: In the 'Sound/Recording' window, right-click and there's an option to see the disabled devices, which then can be enabled.

I had expected the internal microphone to be disabled automatically when an external one is connected. For an usb microphone, it seems that this is not the case, according to a comment under here.

I do not know about the line-in jack. But mine are both active if both enabled

But a fair albeit manual method would be to disable/enable the micro under 'Sound/Recording' as I did in the first place.

Also, I think that it is more reasonable to un-check "Show disconected devices" on right click on 'Sound/Recording' window. In this way, a disconnected device would be absent from the list - as enabling/disabling an absent device is pointless.
