My new Window 11 desktop will not reproduce 5.1 audio surround sound.

About two weeks ago I unpacked my new desktop. This new computer was required in order to run Windows 11. After downloading all the Windows 11 and EDGE updates I plugged in my 5.1 speaker system. First, I made all the necessary changes to both the Realtek Audio Console window and the Windows 11 System > Sound > More Sound Settings windows. Including Speaker Properties and Setup to reflect my 5.1 audio setup. I successfully ran the test tone to all six speakers from both the Realtek Audio Console and the Windows 11 System > Sound > >Speaker Setup Test Tone window. I then tried to play a song from the internet. To my surprise, I only had stereo audio output from my Front Left and Right speakers, and bass from the subwoofer. I immediately went to the Microsoft Community website for a fix. None could be found that cured my issue. However, I did read in one write-up that under “System Sound Output” change Mono audio to “On” and this would work. I did this and successfully sent the “Mono” audio to all six speakers. Does anyone out there really know how to fix Windows 11 so it will generate 5.1 surround sound audio to six attached speakers?

    You need to turn on "speaker fill" in realtek audio console.

    If your realtek audio console doesn't have "speaker fill", then you have to turn on similar features such as "upmix" in studio sonic if you have an asus motherboard.

    Thanks JosephT71 for the quick response. I do have "Speaker Fill" turned on in the Realtek Audio Console" window, with no effect. However, I do have an ASUS motherboard. So, can you walk me through how to locate studio sonic and the "upmix" feature. I did a cursory search and could not find it. Thanks in advance.

    Thank you for the quick response. Prior to writing this help request I completed several of your trouble shooting suggestions. See below.

    • First of all, verify Audio Source Compatibility: Normally over the years I only listened to YouTube, Bing, and my own CD music recorded and stored on my desktops. The audio would always emanate from all six 5.1 system speakers. Apparently, Microsoft was up-mixing the stereo and mono audio to resemble 5.1 surround sound because it certainly sounded great.
    • Run the Audio Troubleshooter: I ran Audio Troubleshooter several time. It could not find anything wrong. Once it allowed me to write a note to higher headquarters describing the issue. No response received.
    • Next, Check the Default Audio Format: I did, several times, see my original note.
    • You can also try to enable Spatial Sound: I did, Windows Sonic only works with headphones and not speakers.

    -Also, open the Realtek Audio Console and ensure the speaker configuration is set to 5.1. and disable any enhancements or effects that might interfere with surround sound: I did, see my original note.

    Hello, I am Riaz H, an independent advisor.

    I can understand your concern and am sorry for the inconvenience.

    I would suggest you the following steps to help you troubleshoot and (hopefully) resolve the problem:

    First of all, verify Audio Source Compatibility

    Make sure the audio source (e.g., the song or video you're playing) supports 5.1 surround sound. Many online streaming platforms only provide stereo audio unless you have a premium subscription or specific settings enabled.

    Run the Audio Troubleshooter

    • Go to Settings > System > Troubleshoot > Other Troubleshooters.
    • Run the "Playing Audio" troubleshooter and follow the recommendations.

    Next, Update or Reinstall Audio Drivers

    • Open Device Manager (search for it in the Start menu).
    • Expand 'Sound, Video, and Game Controllers'.
    • Right-click your audio device (e.g., Realtek) and select 'Update Driver'.
    • If updating doesn't work, uninstall the driver and restart your computer. Windows will reinstall the driver automatically.

    Next, Check the Default Audio Format.

    • Open Control Panel > Sound > Playback tab.
    • Select your 5.1 speaker system and click Properties.
    • Go to the Advanced tab and ensure the default format is set to a 5.1-compatible option (e.g., 24-bit, 48000 Hz).

    Test different formats to see if it resolves the issue.

    You can also try to enable Spatial Sound

    • Right-click the speaker icon in the taskbar and select Sound Settings.
    • Under 'Output', click your speaker system and select 'Device Properties'.
    • Scroll down to 'Spatial Sound' and enable it (e.g., Windows Sonic for Headphones or Dolby Atmos, if available).

    Also, open the Realtek Audio Console and ensure the speaker configuration is set to 5.1. and disable any enhancements or effects that might interfere with surround sound.

    Let me know if any of these steps help or if you need any further help. Thanks
