Windows 10: Why do my sound input and output keep flicking between devices? I have a Behringer...

Why do my sound input and output keep flicking between devices? I have a Behringer interface plugged in and it only happen s when it is.

:)

 

no input or output audio devices found

Unfortunately, that did not work. There is something listed under the sound now in the device manager and that says it is functioning, but i still have no sound and it states there are no input and output devices.

 

No audio input or output devices found

After the last update of Windows 10, no audio devices are listed

Searching in the device manager: all audio devices say it works fine

The sound setting says: no output or input devices were found.

 

Windows 11: Behringer UMC202HD not working, and listed multiple times in Device Manager. Drivers not recognized?

I use a Behringer UMC202HD as an audio output device.
After upgrade to Windows 11, it worked for a while, stopped working, worked again, and now has stopped working again.

The device is recognized by Windows:

• Visible (and can be selected) via taskbar speaker icon
  
• Visible (and can be selected) as speaker in the device settings of Teams
  
• Visible (and can be selected) as speaker in Zoom
  

When selected, however, it does not work:

• When UMC202HD selected (via taskbar speaker icon) prior to start of Youtube-video, Youtube will show the "I'm thinking" circle (the successor to the hourglass), and not progress.
  Video will start as soon as other speakers are selected, with sound on those other speakers.
  
• When UMC202HD selected (via taskbar speaker icon) during a Youtube-video, Youtube will show the "I'm thinking" circle on top of the video (which will continue to run), and not provide any sound.
  When selection changed back to other speakers, circle will disappear, and sound will re-appear (on those other speakers).
  Video will freeze for a while, and then resume (in sync with audio)
  
• When UMC202HD selected as speaker in Teams, there will be no sound, and the message "Your speakers aren't working" will appear after a while
  

I disconnected the device (physically), removed it from Windows (after that: device no longer visible in Device Manager), installed the latest drivers (version 5.51) using the Behringer-provided setup.exe. I then reconnected the device. Still not working.

Weird thing (but it may be standard behaviour): the UMC202HD appears four times in Device Manager:

• In folder "Audio inputs and outputs" as "IN 1-2 (BEHRINGER UMC 202HD 192k)" and "IN 1-2 (BEHRINGER UMC 202HD 192k)", with message "No driver files are required or have been loaded for this device" (when clicking the Driver Details button)
  
• In folder "BEHRINGER USB 2.0 Audio" as "BEHRINGER UMC 202HD 192k", with driver
  
  • C:\WINDOWS\system32\DRIVERS\umc_audio.sys
    
• In folder "Sound video and game controllers" as "BEHRINGER UMC 202HD 192k", with 6 drivers
  
  • C:\WINDOWS\system32\DRIVERS\dmk.sys
    
  • C:\WINDOWS\system32\drivers\ksthunk.sys
    
  • C:\WINDOWS\system32\DRIVERS\portcls.sys
    
  • C:\WINDOWS\system32\DRIVERS\umc_audioks.sys
    
  • C:\WINDOWS\system32\SysFxUI.dll
    
  • C:\WINDOWS\system32\WMALFXGFXDSP.DLL
    

As a comparison, I checked another (working) audio device (an MXL USB microphone). It appeared twice:

• In folder "Audio inputs and outputs" as "Microphone (10- USB audio CODEC)", with message
  
  • "No driver files are required or have been loaded for this device" (when clicking the Driver Details button)
    
• In folder "Sound video and game controllers" as "USB audio CODEC", with 6 drivers:
  
  • C:\WINDOWS\system32\DRIVERS\dmk.sys
    
  • C:\WINDOWS\system32\drivers\ksthunk.sys
    
  • C:\WINDOWS\system32\DRIVERS\portcls.sys
    
  • C:\WINDOWS\system32\DRIVERS\USBAUDIO.sys (only one different from the UMC202HD)
    
  • C:\WINDOWS\system32\SysFxUI.dll
    
  • C:\WINDOWS\system32\WMALFXGFXDSP.DLL
    

Two questions:

1. Is the extra listing (in folder "BEHRINGER USB 2.0 Audio") standard behaviour for devices with drivers that require device-specific drivers)?
   
2. Is there a solution to get the UMC202HD working again?
