Hi, Marc,

That would explain a lot; why one day it worked and the next time I signed on it didn't.  It's one more way that Microsoft can screw up its users.  It is definitely the reason why we converted our remote operation server from a PC laptop to a Raspberry Pi 4B - No more unwanted "updates".  If it's working, leave it alone.

I saw some news items a few days ago.  This is from Google AI:

The September 2026 Windows 11 security update (KB5124008) is causing widespread audio failures, specifically affecting USB Audio Class 1.0 devices with a "Code 10" startup error.[1 <https://redmondmag.com/articles/2026/09/16/microsoft-emergency-windows-update-fixes-only-part-of-usb-audio-problem.aspx>]
I am not a Windows person but this seems to coincide with the issue.

*Current Outage Details*

  * *The Cause:* The September 8 security patch breaks legacy USB
    audio peripherals (headsets, speakers, and mics) that rely on USB
    Audio Class 1.0.[1

<https://www.windowscentral.com/microsoft/windows-11/windows-11s-latest-update-broke-my-speakers-and-im-not-alone>]

  * *Symptoms:* Zero audio output, volume controls stuck at zero,
    unresponsive sound settings, and Device Manager showing "This
    device cannot be started (Code 10)".[1
    
<https://www.pcworld.com/article/3241102/windows-11s-audio-bugs-wont-be-fixed-until-october.html>]

  * *The Fix Status:* Microsoft's emergency out-of-band updates have
    only partially resolved the issue, and a comprehensive cumulative
    fix is expected during October's Patch Tuesday.[1

*Temporary Workarounds*

  * *Switch Audio Modes:* If your USB device supports switching from
    multi-channel/3D audio down to a standard 2-channel stereo
    configuration, it may temporarily restore sound.[1

<https://redmondmag.com/articles/2026/09/16/microsoft-emergency-windows-update-fixes-only-part-of-usb-audio-problem.aspx>]

  * *Use Non-USB Audio:* Route your sound through a regular 3.5mm
    audio jack or a direct wireless Bluetooth connection instead of
    the affected USB port.[1
    
<https://www.zdnet.com/business/windows-11-out-of-band-update-fixes-audio-glitch/>]

  * *Reinstall Drivers:* Open Microsoft Device Manager, right-click
    your problematic USB audio device, select *Uninstall device*, and
    restart your PC to force Windows to re-enumerate the hardware.[1

Lance,
Really need more information to make a guess on this.  Wonder if wfview is running ok, is it controlling the rig? Does WSJT-X run ok alone with the rig? Having had similar things to this happen here, my guess would be that somehow the WSJT-X audio settings have changed and need to be reset.  If you're having trouble with rig control, perhaps the usb port assignment to the rig has changed. That happens here sometimes with my linux system.
Hope you find the help you need and get things in order.

My FT-8 system uses wsjt-x and wfview running on a Windows PC. Installation was easy and it worked great.  Then I went on vacation and now a week later, nothing works.

A friend suggested that maybe a recent update from Microsoft in the PC's OS might be causing the trouble, since nothing else changed.  But what could it be?  Any ideas?
