Check surround sound settings. Right click Speaker in taskbar, choose Sounds. Click the Playback tab. Click properties button for current speakers. Check the Levels tab and Enhancements tab settings for any channel issues. What you describe is what tends to happen when center channel settings are wrong.
Other, less likely thought is audio/video codec problems. Windows 10 should have all the ones you need for common media, but some other program may have over-written some of the native windows software. A little harder to fix than a forum post, but you can google "fixing windows 10 audio codec problems" to help get proper instructions.
Good luck, audio problems can be the worst. One last thought... unplug any headphones that have their own audio controls and see if it is still happening.
