Windows 10: Cannot enable any audio input devices

Hi everyone,I'm running Windows 11 Pro on an HP ProBook 450 G8. It has an Intel CPU which also delivers and controls the RealTek audio output and input.I don't know how or when, but every single audio input device has become disabled. And no matter what I try, I cannot re-enable any of them. The only one I'm really interested in, is the internal mike that is part of the laptop hardware and uses the RealTek OEM driver.I've tried the audio troubleshooter, the Intel drivers tool, updating the Windows drivers, stopping and restarting the service. No matter what I try, whenever I go to re-enable th

Re-enable audio device

Hi,

I would be happy to assist you.

Before we proceed with troubleshooting, I would need little information on the issue.

• Are using speakers / head phones to listen to audio?

If you have disabled the audio device, then you might not see it under the list of playback devices. I would suggest you to follow these steps to make sure you see the disabled devices:

• • 
    Open
    Control panel.
    
  • 
    Click Hardware and Sound and then Click on
    Sounds.
    
  • 
    Under Playback tab, right click on the empty area and make sure
    “Show Disabled Devices” has a check mark on it. If headphones/Speakers are disabled, it will now show up in the list.
    
  • 
    Right click on the device and
    Enable it. Click OK.
    

If the issue still persists, try enabling speakers automatically using steps below.

• 
  Go to Settings> Click on themes> Advance sound settings> right click on the speakers or the audio device youo have connected > click on
  Configure device.
  
• 
  Test the sound level you want, click Next.
  
• 
  And configure the audio devices.
  

Hope this helps you. Do reply if you need further assistance on Windows 10.

Thank you.

 

HFP devices no longer show as audio input or audio output devices (Win11)

All of my HFP Bluetooth devices are no longer available as audio input or output devices. A2DP devices still show as audio output devices.

I've tried:

• unpairing and repairing BT devices (Sony MDR-ZX770BN and a custom ESP32-based device)
  
• removing all BT devices (including hidden devices) from Device Manager, including the RFCOMM and SDP services and Intel wireless driver, etc. and reinstalling
  
• removing the Audio devices (Realtek) and reinstalling
  
• sfc /scannow (no problems found)
  
• checked registry Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Bluetooth\Audio\Hfp\AudioGateay and ..\HandsFree and both show registry value Enabled=1 (not that I've seen any diagnostic ever suggest checking these keys)
  
• pairing my headphones to a Win10 laptop, which works fine, and audio input/output devices allow me to select HFP (also A2DP)
  checking the headphones under "Control Panel\Hardware and Sound\Devices and Printers", I can confirm under "Bluetooth Services" the headphones show Audio Sink, and Hands-free Telephony, so SDP has discovered the HFP profile correctly
  
• my ESP32 device also has SPP (serial port) which works fine, and the headphones can use A2DP just fine, so Windows can use the other BT profiles on these devices
  
• running troubleshooter for Audio Input and Audio Output devices - the troubleshooter finds nothing, and doesn't even list the HFP device as an audio device
  

HFP was working OK before Christmas. At some point since then all HFP devices no longer show as audio input/recording sources or output sources.

My laptop is a Lenovo Thinkpad L15 gen 3, roughly 1 year old. Windows and drivers are all up-to-date.

 

Enable/Disable Audio devices

Hi,

I want to enable/disable audio devices listed in sound control panel (mmsys.cpl) but either through programmatically or through any power shell commands/scripts.

I tried using WMI APIs, Core Audio APIs, pnputil, devcon utilities. But with any of these I am either able to enable/disable an audio endpoint from (AudioEndpoint class) or a media device (Media class). None of these provide similar behavior what we get when disabling audio device through right clicking on it in sound control panel.

Observations:

1. If I use device id of an AudioEndpoint to disable, it gets disabled only in device manager under 'Audio inputs and outputs' section, but not in sound control panel or any other application which are using it.

2. If I use device id of a Media to disable, it gets disabled in device in device manager under 'Sound, video and game controllers' section, but removes the devices completely from sound control panel.

3. If I disable the device from sound control panel by right clicking on it, it gets disabled and unavailable for all apps immediately. It also gets removed from 'Audio inputs and outputs' section in device manager but no impact in 'Sound, video and game controllers' section.

I want to achieve this observation (3) through program or commands.

Please suggest how to do it.

Thanks.
