Step-by-step fix
- Open Settings → System → Sound and select the correct output device (laptop speakers, headphones, HDMI/monitor, etc.).
- Check the volume isn't muted or at zero — system volume and any app volume.
- Unplug and replug headphones; if using Bluetooth, reconnect the device.
- Run the CheckMyMic speaker test — play the left, right and both-channel tones.
- Still silent? Update the audio driver and restart Windows 10.

Only one speaker works — how do I fix the balance on Windows 10?
Open the speaker test and play Left then Right. If one side is silent, check the balance/pan setting in Settings → System → Sound.
