Many people face a situation when the microphone on headphones does not work, or instead of a clear voice stream, transmits a loud, growing noise. To understand the cause of the problem and cure it, it is necessary first to diagnose the system and hardware.
Driver failure is a common issue with Windows 7. If you own this operating system, pay extra attention to checking the functionality of the maintenance programs.
Go through the following verification process:
If you see sound vibrations on the screen, reflected in the corresponding window, the device is in good condition, and the malfunction is related to the computer's system settings.
Some of the most common reasons why the microphone can stop working are as follows:
The majority of headphone issues pertaining to audio or voice transmission are typically due to a faulty wire. The sections of the wire most susceptible to damage are:
The problem can be detected by bending the cable in the risk areas – the signal will appear and disappear, or you will find a position where it becomes stable. You can check the signal if you have a multimeter and experience with using it.
Certain devices, particularly older headphones, might possess distinct circuit designs. If you locate the broken segment, it's possible to re-solder the cable. However, if you lack prior experience with a soldering iron, it's advised to seek professional help from a service center.
Take note: It's only cost-effective to repair if the headphones are of high quality. Repairing low-cost headsets isn't typically practical as it's more economical to simply purchase a new pair.
The lack of signal can be caused by dirt on the plug or headphone jack. In addition, contacts can become oxidized, and connectors are often clogged with debris, especially for smartphones. Thus, carrying your device in a bag or pocket can cause dust and small threads to accumulate in the input. This disrupts the signal path.
You can remove debris from the plug with a thin wire, but this is risky, so it is recommended to buy a can of compressed air. It is relatively cheap and is available at any digital store. To clean the plug, you should use absorbent cotton soaked in alcohol. It is not a good idea to scratch or scrape off the dirt with a knife, as damage to the surface can cause oxidation.
One potential issue causing your headphones' microphone to malfunction could be the absence of the necessary audio card software. This audio card could be either integrated within the motherboard or an individual component. No matter the setup, it's crucial to obtain the appropriate driver from the laptop maker's website or the respective hardware (motherboard/audio card).
You can determine if the driver is causing the issue by accessing the Hardware Manager. Here, you can select "Audio, video, and gaming devices" to display the list of connected devices. A red or yellow indicator next to a device would signal an issue.
It's also possible that the software could be outdated. You can identify the hardware name and attempt to auto-update the driver via the function menu. Nevertheless, a more reliable approach would be to manually download and install the updated driver.
Sometimes an incorrect operation is caused by a system failure – the microphone may be forcibly disabled.
If the connection is made to a device with a built-in microphone, it may work by default – and the headset microphone is not active. In this situation, two microphones are indicated in the equipment list. You only need to select the desired one and activate the "default" button, if necessary, so you do not have to switch manually every time.
In the Windows 7 operating system, the problem with the headset can also occur if it is connected to the front instead of the back. You may have mixed up the headset connectors, which results in the complete inoperability of the headset.
Microphone-equipped headphones are a type of device that frequently experience issues. If you're seeking longevity from your headset, it's wise to opt for reputable brands like Bludi, Sony, Phillips, among others.
