Microphone device [...} was not migrated due to partial or ambiguous match.

[Andreas_1]

This stopped working just on August 3rd, but it was working up until that point.  This seems to be a copy of this issue, and I have tried everything suggested there without success. I do have some additional information though.

To recap:

In the Windows Sound settings, the internal microphone, "Microphone array (Intel Smart Sound Technology)", is detected and works (records sound, when I speak, the slider moves), but in any other program or app (google chrome, Mozilla Firefox, Windows Voice Recorder, etc...) no sound is recorded. The working microphone array is selected, and in Windows Microphone Privacy Settings all the apps are allowed, and when they are running it even shows that the app is currently using the microphone. But, no sound is recorded.  However when I plug in earphone, their microphone records the sound fine everywhe, in settings and in all apps.

Now, when I go to Device Manager, and look at the Events for this device, on 2020-08-03 I see three events:

- Device not migrated

- Device configured (audioendpoint.inf)

- Device started

When I click on "Device not migrated", it says:

Device SWD\MMDEVAPI\{0.0.1.00000000}.{5cde2fe1-7731-47cf-9e2f-0efc0365ed50} was not migrated due to partial or ambiguous match.

I have uninstalled the driver and restarted the computer, but no change. 

This has ruined two business meetings for me in the past week, so I really want to get this working.

Many thanks for any help!

I reviewed your post and I understand that the microphone is not working on the computer.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps.

1. Run Audio Troubleshooter

  - Launch Troubleshooting by typing and clicking “Troubleshooting” in   

     Windows search.

  - Click on "Playing Audio".

  - Follow the on-screen instructions.

2. Check if microphone isn't disabled.

  - Right click on the Volume Icon on the taskbar, select "Recording Devices".

  - Click on "Show disconnected devices", and "Show disabled devices".

  - Select on Microphone, click on "Properties". If it is disabled, enable it.

  - Once enabled, set Microphone as default audio input device.

3. Check if microphone isn't muted.

  - Right Click on the Volume icon on the taskbar, select "Volume Mixer".

  - On the Microphone slider, slide it up to 100%.

4. Boost sensitivity of Microphone

  - Right Click on the Volume icon on the taskbar, select "Recording".

  - Double click on Microphone.

  - Open the Levels Tab, move the Microphone boost slider up to check audio.

5. Disable enhancements

  - Right Click on the Volume icon on the taskbar, select "Recording“, Double

     click on Microphone.

  - Open the Enhancements / Effects Tab.

  - Check "Disable All Sound / System Effects“. Click Apply, OK, test the Microphone again.

6. Change format of the Microphone

  - Right click on the Volume Icon on the taskbar, select "Recording Devices".

  - Double click on Microphone.

  - Go to the Advanced Tab, choose any of the 16 bit options on the list.

Let me know how it goes and you have a great day!

Thank you!

After step #1 the microphone is now working through Voice Recorder again!  Very nice.

But, the Troubleshooter reported "Audio services not responding             not fixed". 

And, when I right-click on the volume icon on the taskbar, I don't have a "Recording Devices" option these days. I don't know if I've ever had that in Windows 10 or if it has disappeared more recently.

But, despite the lingering problems, the microphone does seem to work again now.  

Thanks again.

Perfect, I am really glad to hear that!

If any other questions arise, please feel free to write back to me.

None of these suggestions solved the problem for me. (I do not have a 'record ..' option either.

I have tried everything, including uninstalling the Microphone array so it would reload at system restart. Same problem: audio endpoint.

Please help. All business work is now Zoom - difficult when I am tethered to plug-in headphone mike.

If I view Microphone Array properties from 'Sound - Recording - Microphone Array (selected) I get different properties display:
