At some point, after the May update I lost all PC audio! I've done all the 'no sound' troubleshooting suggestions from Microsoft and everywhere else. I reinstalled all audio drivers, you name it. I even shut down my MSI onboard HD audio in bios and purchased a

Soundblaster Audigy RX sound card, No dice. bought Driver Booster Pro and updated them drivers. Wasted cash!

It's as if the sound just can't get to my output jacks. Foobar doesn't work, NO audio!! You can see the level meters pulse when you test the sound devices. When I unplug the connectors going to my preamp, they pop and buzz so I know the cables to the analog stuff are hot.

I NEED HELP AND I NEED IT FAST!! I'm starting to TWITCH!! I believe it's Microsoft's doing.

    May I get the regkey from you? I'm having the same issue where the value shows as Zero-Length Binary Value

    Here is some more context, I worked with a member of Microsoft Support team to help narrow it down as Im sure you were aware this issue was quite frustrating.

    I was waiting to see if Junes patching would also fail in some cases and break users machines here is what I know.

    • The issue only occurs with patch KB5003169
    • Not everyone is affected only users who experience the following: Patch installs but fails, and retries 2-3 times. After it is installed users have the following issues.
      • Issue #1: Have No Audio (Red X)
      • Issue #2: users now have to hit Ctrl Alt Del at log on (depending on your company policy this may be a change)
    • This affected multiple companies as seen here for Microsoft or here for Dell.

    Solutions Shown Below. Since this issue has not occurred with the latest patches I believe we can close this case. Not sure if Microsoft wants to address this issue with other customers that may not be aware.

    ISSUE #1. It appears that monthly patch that failed was causing the follow registry key to break.

    consolesecurity located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations

    The ConsoleSecurity shows as Zero-Length Binary Value

    However, it should appear as

    Import the registry key (I have regkey if needed) to affected user to resolve this issue.

    ISSUE #2 - All users that have this issue also have another issue where they are required to use CTRL ALT DEL to log in

    This is related to Local Security Policy being changed

    Users were changed to

    Changing this to enabled fixes it
