Sound issues with OpenShot running in Windows 10 are challenging to troubleshoot. Wrong settings may cause several sound issues in Windows. They can prevent hearing sound during playback in the interface, during encoding, or even mute sound in third-party programs while OpenShot is opened. Suggestions were taken from the discussion in https://github.com/OpenShot/openshot-qt/issues/3116.

  1. Try resetting OpenShot to its default settings. Open File Explorer and delete the C:\Users\(USERNAME)\.openshot_qt folder. Removing this folder removes settings and many things that can, in theory, become corrupt. OpenShot automatically recreates the folder with the default settings when you relaunch the program.  This folder is not deleted when the program is uninstalled, so your previous settings are saved, often causing projects to fail.
  2. Ensure that the Playback Audio Device is set correctly for your sound interface/output under Preferences in the Preview tab. (Speakers vs. headphones, line out vs. USB vs. Bluetooth, etc.) Since it is a setting, you will need to restart OpenShot. Perhaps try a different audio device (USB, audio over HDMI from the video card, etc.) to rule out other clip audio issues.
  3. Check that the Default Audio Sample Rate and Default Audio Channels are set to match your hardware. Playback devices > the_device_name > Properties > Advanced tab.
  4. Disable automatic sound suppression for voice calls during microphone activity. Playback devices > the_device_name > Properties > Communications > Do nothing.
  5. Try disabling 'Audio Enhancements' under the advanced settings tab of your audio device.
  6. For headphones, first, plug in the headphones and then start OpenShot afterward. https://github.com/OpenShot/openshot-qt/issues/2565 
  7. Ensure that you have the latest security updates from Microsoft.  You may have to use the Windows 10 Update Assistant to update your Windows to the latest security patches.
  8. Ensure that your device drivers are updated to the latest WHQL certified versions.  You can download and install a free software device driver update tool to check your device drivers and download updated versions if needed.
  9. Download and install the latest Daily Build from our website.  Before installing the Daily Build, the best approach is to uninstall OpenShot from the Control Panel or the Apps panel in Settings (Windows).  After uninstalling OpenShot, delete the C:\Program Files\OpenShot Video Editor and C:\Users\(USERNAME)\.openshot_qt folders.  After deleting the folders, install the latest Daily Build and launch the program.
