One Earbud Not Working on Windows: Left/Right Channel Fix
Fix single-sided audio by checking balance settings, mono mode, and device reset.
If audio only comes from one side:
- Go to Settings > System > Sound > Output > Device properties.
- Check Left/Right balance and set both to 100.
- Disable Mono audio in accessibility sound settings.
- Reconnect the earbuds and test with another app.
- Test the earbuds on a phone to rule out hardware failure.
If one side still has no sound on all devices, the earbud may need replacement.
