No audio output: Win 10 Pro

Hi Nelson,

We would like to know more about your concern regarding the audio output of your computer. Have you received any error messages? After checking the audio drivers on the
Device Manager, have you updated the audio drivers on your computer?

I would suggest you to check again the Device Manager and follow the steps below:

• In the Control Panel, remove the given sound software
• Remove also the sound driver of the computer in the Device Manager
• Restart the computer
• Open Device Manager and click Scan for hardware changes
• If there are no audio device that can be detected by the computer, you can update the chipset driver from the manufacturer's website.

Please keep us posted for us to assist you further.

 

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.
