When playing music or watching videos on a computer, sound distortion or characteristic crackling may occur. The reasons for this phenomenon can be both software and hardware.
Sound distortion can be caused by the speakers through which you are listening to music. Examine the cable with which the speakers are connected to the computer, check if there is any interruptions on the cable, if the cable wire is connected to the right connector. Just in case, unplug the wires and plug them back in. If the speakers are plugged into the USB port, test the sound by plugging the device into another similar port. Re-read the documentation that came with your speakers to make sure they are connected correctly. If there is no documentation, open the manufacturer's website and find the user manual there. Also, distorted sound on the computer can be caused by mechanical damage to the speakers. To verify that the problem is in the physical state of the playback device, try connecting other audio equipment, such as headphones or other speakers, to your computer and listening to the sound using them. If distortion is present, your speakers are in need of repair. If the distortion persists, there is either a problem with your sound card or with the software. Check the sound options just in case, to do this, right-click on the speaker icon in the system tray of your desktop. See if the Mute Sound checkbox is checked. When you play sound on your computer, it may be distorted due to improperly installed sound card drivers. Install newer drivers to fix this problem. Realteck software is suitable for most sound cards. To download this driver, go to realtek.com/downloads, select your operating system version and download the required programs. Then install them on your computer. Reboot the system and check audio playback. Older sound cards may experience audio mute after the computer wakes up from sleep mode. In this case, reboot the system and check the sound.
