How to Fix Realtek Digital Output No Sound
Some Windows users may encounter the issue of no sound from the Realtek digital output, affecting normal audio output. This article provides effective solutions to help you quickly fix the issue and restore normal audio output experience.
1. Check Hardware Connections
Ensure that your audio output device is correctly connected to your computer. For HDMI or optical output, check that the connections are secure and all cables are properly inserted.
If you're using HDMI or optical cables to connect your sound system, try replacing the cables or changing the port. Damaged cables or loose connections may prevent proper audio signal transmission.
2. Update Device Drivers
Outdated or corrupted drivers are one of the common causes of audio output problems. By checking for updates to your Realtek drivers, you can resolve driver-related audio issues. It's recommended to use Driver Sentry for automatic driver updates, which saves time and prevents the risk of downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
After scanning, it will display the drivers that are missing or need updating. Find the Realtek audio driver in the results list and click the "Upgrade" button.
Once the update is complete, it's advised to restart your computer to ensure the updated drivers take effect.
3. Set Default Audio Device
Right-click the volume icon in the bottom right corner of the screen and select "Sounds".
Go to the "Playback" tab, select the Realtek digital output device, and click "Set Default" at the bottom.
Click "Apply" and "OK".
4. Disable Audio Enhancements
In the "Sound Settings" window, click "Device Properties" under the "Output Devices" section.
In the device properties window, switch to the "Enhancements" tab.
Check "Disable all sound effects" or disable all audio enhancement features.
Click "Apply" and "OK" to save the settings.
After completing the setup, play an audio or video file to check if the sound output has returned to normal.
5. Check Audio Format Settings
In the "Sound Settings" window, find and select your Realtek digital output device.
Click "Device Properties", then go to the "Advanced" tab.
In the "Default Format" section, make sure the audio quality settings suitable for your device are selected. It is recommended to choose "16-bit, 44100Hz (CD Quality)" as a test audio format.
Click "Apply" and "OK" to save the settings.
6. Check for System Updates
Press "Win + I" to open the "Settings" window.
In the Settings window, select "Update & Security".
Click "Windows Update" > "Check for Updates". The system will automatically search for and install any available updates.
If there are audio driver or system updates, install them. Windows typically fixes known hardware compatibility issues through updates.
Once the updates are installed, restart your computer and check if the Realtek digital output has restored normal audio output.
By following the above methods, you can effectively resolve the issue of no sound from the Realtek digital output. If the problem persists, it is recommended to contact professional technical support for further troubleshooting.
