If you're experiencing no audio on HDMI monitors and the system does not recognize the speakers on the monitor's audio output portthere are a few steps you can take to troubleshoot the issue:
- Check Connections: Ensure that the HDMI cable is securely connected to both the monitor and the PC. Sometimesa loose connection can cause audio issues.
- Set HDMI as Default Playback Device: Right-click the speaker icon in the system trayselect "Playback devices," and check if the HDMI output is set as the default device. If notright-click on it and select "Set as Default."
- Update Audio Drivers: Make sure that your audio drivers are up to date. You can do this through Device Manager by expanding the "Soundvideo and game controllers" sectionright-clicking on your audio deviceand selecting "Update driver."
- Check Monitor Settings: Some monitors have their own audio settings. Ensure that the volume is turned up and that the monitor is not muted.
- Run Windows Troubleshooter: Since you mentioned that you ran the troubleshooter without successensure that you are using the audio troubleshooter specifically. You can access this through Settings > Update & Security > Troubleshoot > Additional troubleshooters > Playing Audio.
- Test with Different HDMI Cable/Port: If possibletry using a different HDMI cable or connecting to a different HDMI port on the monitor to rule out a faulty cable or port.
- Check for Windows Updates: SometimesWindows updates can resolve compatibility issues with audio devices. Make sure your system is fully updated.
If none of these steps resolve the issueit may be worth checking if the monitor itself has any known issues with audio output or if there are specific settings that need to be adjusted.
