Windows 10: Audio output is working but Audio input not working

Audio input is simply not working and ive tried everything.

:)

 

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.

 

audio is not working?

Hello Tanzila,

Thank you for using Microsoft products and posting to the community.

I'm sorry to hear that you're having trouble with your audio. Audio problems can have a variety of causes, and at this time I'd like to start with the following information in order to gain a better understanding of your situation and offer advice.

1. I'm wondering if by audio not working you mean the audio input or audio output is not working properly? Or does it mean that both of them are not working properly?



2. I would like to know when this started happening? Did you make any changes before that?



3. I would like to know if the audio is not working properly when you are using external speakers or headphones? Or are you experiencing this problem using your computer's default speakers and microphone?

Alternatively, if you have not tried some of the troubleshooting steps on your own, then you can try the following basic troubleshooting steps first.

1. Check Audio Device Connections:
   
   • Ensure that your audio devices (e.g., headphones, speakers) are properly connected to your computer or device. If you're using external speakers or headphones, make sure they are plugged in correctly and powered on.
     
2. Audio Output/Input Selection:
   
   • Verify that the correct audio output/input device is selected in your system settings. In Windows, right-click the speaker icon in the system tray and select "Open Sound settings" to check the output/input device.
     
3. Update Audio Drivers:
   
   • Outdated or incompatible audio drivers can cause audio problems. Check the manufacturer's website for your computer or sound card to download and install the latest audio drivers.
     
4. Run Audio Troubleshooter (Windows):
   
   • In Windows, you can use the built-in audio troubleshooter to diagnose and potentially fix audio problems. Go to "Settings" > "System" > "Sound" > "Troubleshoot."
     
5. Check Audio Settings in Applications:
   
   • Ensure that audio is not muted or set to low volume within the specific applications or media players you're using.
     
6. Test with Different Audio Sources:
   
   • Try playing audio from different sources, such as music files, videos, online streaming, or other apps, to see if the issue is specific to one source or application.
     

Looking forward to hearing from you, by knowing more will help me to provide better support.

Sincerely

| Microsoft Community Support Specialist

 

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.
