Windows 10: External audio device detected when no audio device is plugged

My pc detects audio device when no audio device is plugged.I have not plugged any audio device but there is speaker in playback.

:)

 

no audio device detected

when I plug my headphones into the front panel audio jack, a dialog box pops up, like this one:





Yet sound is turned off. I can look at this dialog box as well:









Any help is appreciated.

 

Does Windows log when you plug in / unplug an audio device from a 3.5mm jack?

When an audio device is plugged/unplugged from the 3.5mm jack, does Windows log that anywhere?

Not by default. You have to write an app to detect plug in/plug out. Note the jack has to support jack-presence detection.

See Device Events - Windows applications | Microsoft Docs for more information and sample code.

You can extend the sample code to log to a file or create a custom user define event in the event log.

Suggestion:

• Add code to use your built in webcam to take a photo of the culprit.
  

 

External audio device

Hi Zarif,

The difficulty that you're experiencing may be caused by corruption in system files or an audio driver issue. For us to isolate the problem, we would like to know the following:

• Did you make any changes to your computer before the issue started?
• Have you tried updating or uninstalling/reinstalling your audio driver? If you haven't, kindly do so.
  
• Do you also encounter the same problem when connecting the external audio devices to another PC?
• Have you taken any troubleshooting steps so far?

In the meantime, we recommend that you run the Hardware and Devices troubleshooter. This program will try to diagnose and resolve the issues that it finds. To do this, follow these steps:

1. In the search field on your taskbar, type in Troubleshooting, then press
Enter.

2. On the left panel, select View all.

3. Click Hardware and Devices.

4. Click Next to run the troubleshooter.

If the issue persists, we suggest using the
System File Checker (SFC) tool. This tool scans and repairs the damaged and corrupted system files on your computer.

Keep us posted and we'll be willing to assist you further.
