Windows 10: My laptop stopped getting audio input from any devices

A few days ago I updated my laptop and when I next used my laptop for a video call my mic was not working. I tried changing my headphones and even tried using wired ones but still the audio input wasn't being detected. I was able to select the input device but there was no input being detected. I tried to run the trouble shooter but it didn't help either. I checked all the volume settings and privacy settings. After a new update it started working again, but the next day it went back to not picking any input. Please help.PS: My device is Fujitsu FMV UH-X 2 in 1.

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.

 

My laptop microphone isn't detected as an audio input device when I plug in headphones.

I have been using a pair of bluetooth headphones for the past couple of weeks with my laptop. I use the audio output of the headphones along with my laptop's built in microphone as it is better quality. Today however, windows stopped recognizing my laptop microphone as an audio input while my headphones are connected. I am able to use the microphone whenever the headphones are not connected. My microphone input is listed as "Microphone Array (AMD Audio Device)" and remains listed while the headphones are connected, but produces no sound and is not detected by programs like Sound Recorder.

It was working fine until I attempted to disable "Handsfree Telephony" to stop the audio quality from lowering. After I re-enabled this setting, I ran into the issue.

 

Remote device doesn’t detect audio input

The problem that the audio input of my laptop is not visible by the remote computer. I did troubleshooting steps such as checked settings, group policy, remote desktop services. No problem. But it remote audio device isn’t picking up input from my
mic.
