No sound in bluetooth headset when OS access its microphone (Win 10)

Super User Asked by grimreaper on January 1, 2022

It used to work properly until recently, but now I can’t make calls over Skype or Viber. When a call starts all audio on my end disables (but the interlocutor does hear my mic).

Audio also turns off when I open audio & video settings in Skype, or the tab “Recording” in the sound settings of the Control Panel.

I tried restarting and reconnecting the headset, disabling and re-enabling Bluetooth, checked off “Allow applications to take exclusive control of this device” on both headphones and the microphone, and it didn’t work.

I haven’t installed any specific drivers, the system automatically recognized the headset when I first connected it. And doesn’t look like this headset even got any.

I also tried launching the troubleshooter and it did not identify any problems, only offered to disable audio enhancements, which I did.

I have been having this same issue as far as I can tell it has to do with the Bluetooth adapter not being able to send and receive at the same time. It can only do one or the other. So when you are in your Audio settings in skype or the recording tab in sounds, it starts to use your mic and thus disables your speaker part of your headphones. as soon as it stops using the mic i.e. you get out of the recording tab or the settings nothing is using the mic anymore thus sound returns to your speakers.

Looking into possible fixes I have tried a lot to no success like the ones listed already. The one thing that I found that could potentially fix the issues is upgrading to bluetooth 5.0 it has double the bandwidth of earlier versions. With the more bandwidth it may allow it to transmit and receive simultaneously.

Just my thoughts.

The problem seems to be that Windows 10 is treating the headphones as a Bluetooth low energy device. To fix:

  1. Unpair your headphones from the computer
  2. Right-click the Start menu and open Device Manager
  3. Expand Bluetooth
  4. Right-click Microsoft Bluetooth LE Enumerator and disable
  5. Pair your headphones
  6. Enjoy

I hope the following method will work:

Open Device Manager from your search bar, scan for hardware changes. Then in Audio inputs and outputs section, look for the driver software for your headphone. Then check for updates.

If this doesn't work, disable the driver then enable it. If you still having audio related issues, uninstall and then reinstall the driver.

If it's the Bluetooth adapter, try connecting other Bluetooth devices to check if it works correctly. If not, please follow the same process with the Bluetooth adapter. It's Device Manager > Bluetooth > Intel(R) Wireless Bluetooth(R) for my laptop. For your device, it may or may not be the same.
