Try these steps in order to stabilize the volume in Windows 11:
- Check output device and basic volume
- Select the Speakers icon on the taskbar.
- Use the arrow next to the volume slider and make sure the correct speakers/headset are selected.
- Confirm the main volume slider is stable and not being changed by a keyboard, headset wheel, or external device.
- Check per‑app volume (Volume mixer)
- Select Start > Settings > System > Sound.
- Select Volume mixer.
- Make sure:
- System volume is set appropriately.
- The affected app’s volume is not very low and not muted.
- If volumes look wrong or unstable, use the option to reset app volumes to defaults (if available in your build).
- Turn off audio enhancements
Audio enhancements can cause volume level changes.
- Go to Start > Settings > System > Sound.
- Under Output, select the audio device in use.
- Find Audio enhancements / Advanced settings and set Audio enhancements to Off.
- Check hardware and connections
- Make sure speaker/headphone cables are firmly plugged in and in the correct jack.
- If using USB audio, try a different USB port.
- Disconnect and reconnect any headphones to see if behavior changes.
- Run the Windows audio troubleshooter again
- Select Start > Settings > System > Troubleshoot > Other troubleshooters.
- In the Audio section, select Run and apply any fixes offered.
- Update or reinstall the audio driver
- Press Start, type Device Manager, and open it.
- Expand Sound, video and game controllers.
- Right‑click the audio device and select Update driver, then restart.
- If the issue continues, uninstall the device from Device Manager and then reinstall the latest driver from the PC or motherboard manufacturer.
If the problem started immediately after updating to Windows 11, also check Start > Settings > Windows Update and install any pending updates, then restart and test again.
