    Realtek Stereo Sound Issues

    I started noticing that in games, some sounds aren't working properly. As an example, in 3D games such as Fallout: New Vegas, Borderlands 2 and Dying Light, the positional audio for character dialog lowers in volume if you are not facing directly at the character. If I turn 180 degrees away from the character, the volume of the character's speech is almost zero.

    I believe what is happening is that the games are incorrectly trying to render 5.1 or 7.1 audio, so when the player turns in relation to the character, it's trying to use side and rear speakers (which aren't there) to render the audio.

    I have everything in Windows sound settings set to 'Stereo'. But in 'Sound Control Panel' in the properties for Realtek High Defintion Audio, the 'Levels' tab is still showing 'Side', 'Center', 'Subwoofer' and 'Rear' level settings. No matter what I do it looks like the driver is trying to render multichannel instead of stereo.

    To confirm this I enabled 'Windows Sonic for Headphones' and the issue goes away, I believe because this mixes the multichannel audio down to stereo. I'm using Realtek HD Audio (I've tried three different drivers and currently have the 6.0.8799.1 installed).

    Finally I uninstalled the Realtek driver and Windows installed its default sound driver and it does not have the issue. It also doesn't show the extra channels in its sound control panel.

    I did see an article about a recent Windows update that affected multichannel sound in games, but it doesn't mention stereo sound or the issue I'm having.

    Can anyone using stereo audio with Realtek drivers confirm this issue?

    Windows 10 Home 1903 (OS Build 18362.356)

    Motherboard: ASRock B450M Pro4 / Realtek ALC892

    Also, I got the recommended audio driver for this board from the ASRock site (8730.1) and installed it, but still have the issue.

    the problem may be the Win10 v1903 KB4515384 update (build 18362.356) as there were reports of this update causing some audio issues with certain games:

    try removing/uninstalling this update and revert to an older 1903 build [18362.329 or older]


    install the newly released KB4517211 update [build 18362.387], which should fix some of the audio issues.

    this new KB4517211 update may appear in Windows Update as an Optional update and will not be automatically delivered. you have to manually search for it from the Windows Update settings app.
