Follow these steps in order to isolate and fix the issue on Windows 11:

1. Confirm Windows is sending audio to the correct device
   • Select the Speakers icon on the taskbar.
   • Select the arrow to the right of the volume slider (Select a sound output).
   • Make sure the built‑in laptop speakers (not headphones, monitor, or Bluetooth) are selected as the output device.
2. Check hardware and basic volume controls
   • Make sure no cables or external speakers/headphones are partially plugged in; a half‑inserted plug can mute one side.
   • Ensure the laptop is not muted and volume is turned up.
   • If any external speakers/headphones are connected, unplug them and test the built‑in speakers again.
3. Turn off audio enhancements
   Sometimes enhancements can cause channel issues.
   • Select Start > Settings > Sound.
   • Under Output, select the device for the laptop speakers.
   • Scroll to Advanced settings and set Audio enhancements to Off.
   • Test audio again.
4. Run the audio troubleshooter from Settings
   (Different from the Get Help app, this is the built‑in troubleshooter.)
   • Select Start > Settings > System.
   • Select Troubleshoot > Other troubleshooters.
   • In the Audio section, select Run and follow the prompts.
5. Update or reinstall the audio driver
   A driver problem can cause one channel to fail.
   • In the search box on the taskbar, type device manager, then open it.
   • Expand Sound, video and game controllers.
   • Right‑click the laptop’s audio device (for example, Realtek or similar) and select Update driver > Search automatically for drivers and complete the update.
   • If that does not help, right‑click the same device, select Uninstall device, check Attempt to remove the driver for this device, and select Uninstall.
   • Restart the laptop so Windows reinstalls the driver automatically, then test audio.
6. Use the generic Windows audio driver (test)
   • Open Device Manager again.
   • Expand Sound, video and game controllers.
   • Right‑click the audio device > Update driver > Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
   • Choose the generic audio driver shown and install it, then test.

If sound still only comes from one side after all software steps, the remaining cause is likely a physical fault in the laptop speaker or internal wiring, which requires hardware service from the device manufacturer or a repair shop.
