When a desktop computer is plugged in with wired headphones and no microphone function is found, it can be checked and resolved from the following aspects: 1. Check the hardware connection
1. Confirm headphone plug: Check if the headphone plug is fully inserted into the computer's audio interface. Some headphones come with a single plug (for audio and microphone), while others have two plugs (one for audio and one for microphone). Ensure that the plug is inserted into the correct socket.
2. Test headphones: Try inserting the headphones into another device (such as a phone) to confirm if the headphones themselves (including the microphone) are working properly.
3. Check the interface: Check the audio interface of the computer for dust or foreign objects, and clean the interface with compressed air if necessary. 2、 Check audio settings
1. Sound Settings: Right click on the volume icon in the bottom right corner of the taskbar and select "Sound Settings"- In the "Input" section, check and confirm if any microphone devices are listed. If not, it may be that the headphone microphone is not recognized- Ensure that the correct microphone device is selected and not muted- Click on 'Device Properties' and check if the volume has been adjusted to the appropriate level- Return to the "Sound Settings" page, click on "Manage Sound Devices", and ensure that the microphone device is not disabled.
2. Recording device: - Open the control panel, find "Sound", and then switch to the "Recording" interface- Confirm if the microphone device is displayed in this list and set as the default device- Double click the microphone device, open the Properties window, adjust the microphone volume in the Level tab, and cancel the mute state. 3、 Update driver program
Drivers are the bridge between hardware and operating systems, and outdated or damaged drivers may cause hardware to malfunction.
1. Access Device Manager: Right click on "This Computer" or "Computer", select "Manage", and then click on "Device Manager" on the left.
2. Check audio devices: Expand "Audio Input and Output" in Device Manager and find your headphone microphone device.
3. Update Driver: Right click on the microphone device and select "Update Driver". You can choose 'Automatically search for updated driver software' to have the system automatically find and install the latest drivers. If updating the driver program does not work, you can try uninstalling the device and restarting the computer to have the system automatically reinstall the driver program. 4、 Check application permissions
Windows 10 and above operating systems have privacy settings that may restrict application access to microphones.
1. Open privacy settings: Open "Settings", select "Privacy", and choose "Microphone" from the left menu.
2. Check permissions: Ensure that the 'Allow apps to access your microphone' option is enabled. Scroll down to ensure that the application you need to use has enabled access to the microphone. 5、 Other possible issues
1. Damaged headphones or microphone: If none of the above steps can solve the problem, it may be due to physical damage to the headphones or microphone itself, and a new device needs to be replaced.
2. Software Conflict: Some software may interfere with the normal operation of the microphone. You can try uninstalling recently installed software or checking relevant settings to see if the problem is resolved.
By following the above steps, you should be able to solve the problem of a desktop computer without a microphone when wired headphones are plugged in. If the problem persists, it is recommended to contact the technical support of the computer manufacturer or seek professional assistance.
