Answer 3

Hi Hubert Lee,

To get the surround setup works as expected, please make sure these conditions are met:

• The media is surround sound format.
• The player supports and outputs surround sound.
• Sound playback is configured as surround:
  • Start > Run > mmsys.cpl
  • Right click on the surround device > Configure Speakers
  • Audio channels: choose the option is right for your setup
  • Follow the prompt

If you have further information, please feel free to let me know.

Answer 4

Use the built-in Windows 11 audio troubleshooting steps to isolate why the rear speakers are silent even though the surround setup test works.

1. Confirm the correct output device
   1. Select the Speakers icon on the taskbar.
   2. Select the arrow next to the volume slider (Select a sound output).
   3. Make sure the surround-capable device (AV receiver/surround speakers) is selected, not a monitor, Bluetooth device, or headphones.
2. Check hardware connections and volume
   1. Verify all speaker cables are firmly plugged into the correct jacks (especially rear channels). Many systems use green for front output and other colors for rear/center/sub; check the manufacturer’s labeling.
   2. Ensure the speaker system’s own volume is turned up and not muted.
   3. If using USB, try a different USB port.
   4. If headphones are connected, unplug them and test again, as some PCs route audio only to headphones when they are plugged in.
3. Turn off audio enhancements
   1. Select Start > Settings > Sound.
   2. Under Output, select the surround audio device.
   3. Scroll to Advanced settings and set Audio enhancements to Off.
   4. Test rear speakers again in normal apps (not just the test tone).
4. Set the correct default audio device
   1. Go to Start > Settings > System > Sound.
   2. In Output, select the surround-capable device as the output. This also sets it as the default.
   3. If an external monitor without speakers is selected as default, change it to the surround device.
5. Update or reinstall audio drivers
   1. Press Start, type Device Manager, and open it.
   2. Expand Sound, video and game controllers.
   3. Right-click the surround audio device and select Update driver > Search automatically for drivers and follow the prompts.
   4. If no newer driver is found or the issue persists, right-click the device again, select Uninstall device, confirm, then restart the PC so Windows reinstalls the driver automatically.
6. Try different audio formats
   1. Open Control Panel > Hardware and Sound > Sound.
   2. On the Playback tab, right-click the default surround device and select Properties.
   3. On the Advanced tab, change the Default Format (for example, try different sample rates/bit depths), select OK, and test audio. Repeat with other formats if needed.
7. Restart Windows Audio services
   1. Press Start, type services, and open it.
   2. Find and restart these services (right-click > Restart):
      • Windows Audio
      • Windows Audio Endpoint Builder
      • Remote Procedure Call (RPC)
   3. Test the rear speakers again.

If the rear speakers only work in the Windows test but not in apps, also check each app’s audio settings (e.g., some games or media players must be set to 5.1/7.1 instead of stereo) and ensure they are using the same output device as Windows.
