SOUDN JUST IN LEFT /RIGHT SOUND IN LEFT

Question

HOW TO SOLVE THIS ,I DONT UNDERATSD WHAT THE ISSUE

Answer 1

Hello, thank you for reaching out to Microsoft Q&A.

Are you only hearing sound from one side, specifically the left speaker?

Please confirm if this occurs with both your laptop's internal speakers and with wired/wireless headphones.

==================================================

Let us run a simple test to check if your left and right speakers are working or not.

Click Windows + R key, type mmsys.cpl and click ok.

Right-click your default audio output device, for example - Realtek (R), select Properties.

In the Advanced Tab, click Test.

See if you get the sound from both the left and right speakers.

Answer 2

Follow these steps in Windows 11 to fix sound coming only from the left or right side:

1. Check left/right balance
   1. Select Start > Settings > System > Sound.
   2. Under Output, click your headphones/speakers.
   3. Under Output settings, select Volume.
   4. Make sure Left and Right are set to the same value (for example, both 100).
2. Turn off Mono audio
   1. In Settings > System > Sound.
   2. In the Output section, find Mono audio.
   3. Turn Mono audio Off.
3. Check the device itself
   • Make sure the headphones/speakers are not damaged and the plug or Bluetooth connection is fully seated.
   • If Bluetooth, fully charge the device, then disconnect and reconnect it from Settings > Bluetooth & devices.
4. Run the audio troubleshooter
   1. Open Settings > System > Sound.
   2. Use the built‑in troubleshooter under Output (or run the audio troubleshooter from the Get Help app as described in the sound troubleshooting article).

If the problem continues on this PC but the same headphones/speakers work correctly on another device, update or reinstall the audio driver from Device Manager and, if needed, from the PC manufacturer’s support site.
