Since sound works in Google Chrome, YouTube, and local video files on the same PC, display, and sound bar, the issue is likely specific to how Edge is handling media playback rather than a general Windows audio failure.
Try these checks in order:
- Verify the media format in Edge
- Open
edge://media-internals in a new tab.
- Reproduce the problem with the video that has no sound.
- Review the player properties and codec details.
- If the same media fails in Edge but works elsewhere, this helps confirm whether Edge is hitting a playback or codec-related issue.
- Compare codec support behavior
- Edge does not natively support all video codecs.
- Some formats can cause partial playback problems, such as audio without video or incomplete playback.
- If the affected content uses a narrowly supported format, test with a different video source or a widely supported format.
- Check Windows Volume Mixer
- Right-click the Volume icon in the taskbar.
- Select Open Volume mixer.
- Make sure the slider for Edge is not muted and is set high enough.
- Also confirm the system volume is not muted.
- Turn off audio enhancements for the playback device
- Right-click the Volume icon and select Sounds.
- Open the Playback tab.
- Select the active audio device, then select Properties.
- Open the Enhancements tab.
- Check Disable all enhancements, then select OK.
- Change the audio format
- Right-click the Volume icon and select Sounds.
- Open the Playback tab.
- Select the active audio device, then select Properties.
- Open the Advanced tab.
- Under Default format, choose a different format and test Edge again.
- Update or reinstall the audio driver
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Update driver.
- Choose Search automatically for updated driver software.
- If that does not help, uninstall the audio device, select Delete the driver software for this device, and restart the PC so Windows reinstalls it automatically.
- Save open work before restarting.
- Install the latest audio driver from the device manufacturer
- If Windows does not find a newer driver, download the latest audio driver for the PC or sound device from the manufacturer’s support site.
- Install it and restart the PC.
- If the issue started after Windows Update, roll back the audio driver
- In Device Manager, right-click the audio device and select Properties.
- Open the Driver tab.
- Select Roll Back Driver if available.
- Make sure Windows is fully updated and restart
- Go to Start > Settings > Update & Security > Windows Update > Check for updates.
- Install available updates.
- Restart the PC, especially if Update and restart is shown.
If the problem only happens on specific sites such as Instagram reels, the most relevant checks are edge://media-internals, Volume Mixer, audio enhancements, audio format, and the audio driver steps.
