If you’re using a desktop computer, you may sometimes hear strange noise from your speakers or headphones. It may sound like a buzz, sometimes playing games or playing movies more intensely. To solve this problem, you have to find out the cause of it.
Where can the acoustic noise come from?
There are many reasons for noise from the sound. They can be roughly divided into two categories: physical speakers and the PC itself.
Determine which part of the sound is faulty.
Check if there is a problem with the audio, just plug them into an audio source other than a PC, such as a cell phone or MP3 player. Please note that it is normal to hear pop-ups and clicks when you disconnect the audio jack and plug it into another device. However, if you continue to hear electronic interference after plugging in the power, you can troubleshoot your PC. You can also perform the same test in reverse: get another set of speakers or headphones and plug them into your PC. If you still hear noise, there may be a problem with your computer.
If the sound is a problem, they are likely to have been damaged. You may listen carefully to determine which setting has a problem. At this time, if the audio warranty period, you need to replace the new equipment or repair.
Reduce PC interference
If you are sure that your computer is a problem, most PCs on the market today have integrated sound cards on the motherboard. But without proper current shielding, it can make the audio jack susceptible to interference from the CPU, graphics card, memory, and all other components in the computer. This can cause clicks or clicks in the audio and headphones.
There are a few things you can do to change this:
Switch to another audio port . Most desktop computers have a headphone jack on the front of the chassis. No matter which one you use, try another one to see if the unwanted sounds still exist. (If you have more than one headphone jack, plug it into the green jack.)
Install the complete sound card . A discrete sound card PCI is connected to the motherboard. They also use dedicated high quality components to output digital and analog formats. It is not difficult to install a sound card – it is basically the same as the steps for installing a graphics card.
Use a USB sound card .
If you can’t open the sound card on the motherboard of your computer, or if your laptop causes sound problems, you can use a USB sound card. When you plug an audio or headphones into the audio jack on an external sound card, other interference is generally avoided. Like standard sound cards, USB models come in a variety of complexities and qualities.
(Note: The USB sound card does not improve the sound of the laptop case speakers.)
