The solution to the current noise or burst sound of Realtek sound card is as follows: 1. Update or roll back the Realtek driver, go to the official motherboard website to download the latest driver or try the old version; 2. Turn off the energy-saving options in power management to prevent the device from frequently starting and stopping; 3. Adjust the audio format and turn off the enhancement function to ensure compatibility of multiple applications; 4. Check the connection of headphones, speakers and jacks to eliminate physical problems. Other possible reasons include background program conflicts, BIOS settings abnormalities, system files corruption, etc. In most cases, it can be solved by updating the driver or turning off the power management. If there is still a problem, it may be a hardware failure. It is recommended to use an external USB sound card instead.

Under Windows systems, it is a common problem to have current noise or burst sound when Realtek sound card appears. It is usually manifested as a slight "sizzling" sound or intermittent burst noise when playing music, video or game. This problem may be caused by driver compatibility, improper power management settings, or hardware interference.

Here are some practical solutions, arranged by common priorities:

1. Update or rollback the Realtek driver

Driver incompatibility is one of the main causes of audio abnormalities. It is recommended to download the latest version of Realtek audio driver installation from the motherboard official website first.

• Go to Device Manager → Expand “Sound, Video, and Game Controllers”
• Right-click Realtek High Definition Audio → Select "Update Driver"
• If it is already latest, try "uninstall the device" and let the system automatically reinstall after restarting
• Or manually install the dedicated audio driver provided by motherboard manufacturers (more stable than the general version)

Sometimes the new driver will cause problems. You can right-click the "Properties" → "Driver" tab and click "Rolling Driver" to try whether the old version is normal.

2. Turn off “Allow the computer to turn off this device to save power”

In order to save energy, the system may frequently start and stop the audio equipment, causing disconnection or noise.

The operation steps are as follows:

• Open Device Manager → Find Realtek High Definition Audio
• Right-click → Properties → Power Management tab
• Uncheck "Allow the computer to turn off this device to save power"

This setting is especially important in notebooks because the default energy saving strategy is more aggressive.

3. Adjust audio enhancements and exclusive access

Some audio enhancements can conflict with the playback content, causing a burst.

• Right-click the taskbar volume icon → “Sound Settings”
• Select the current output device → Click "Device Properties"
• Enter the "Advanced" section and adjust the default format to: 44100Hz or 48000Hz. The bit depth is selected according to the device support.
• At the same time, try turning off the Audio Enhancement feature (if any)
• In the Exclusive Access section, uncheck "Allow other applications to exclusively control this device"

This allows multiple applications to use audio simultaneously without conflicting, avoiding sudden mute or popping.

4. Check the physical connection of headphones/speakers and jacks

Some users actually encounter problems from the hardware itself:

• Is there any problem with the replacement headphones?
• Plug and unplug the headphones several times to ensure good contact
• Try comparing tests using the front panel audio interface and the motherboard rear interface
• Check whether the audio cable inside the chassis is loose (if it is a desktop computer)

Sometimes dust accumulation or poor contact can also cause similar problems.

A brief description of other possible reasons

• Background program conflicts : such as voice assistants, recording software, virtual sound cards, etc., try to close the troubleshooting one by one.
• BIOS setting problem : In rare cases, you need to enter the BIOS to restore the default settings or update the motherboard firmware.
• System file corruption : Run sfc /scannow command to repair the system file.

Basically these common methods are. In most cases, it can be solved by updating the driver or turning off power management. If the problem still exists, it may be hardware aging or motherboard integrated sound card failure, considering an external USB sound card is a good alternative.
