Connect the Bluetooth headset after the computer reboots and the hands-free phone service, which has been turned off, will be turned back on.

Question

This will open automatically after reboot.

Answer 1

Another option to avoid the Bluetooth device entering Hands-Free mode is to disable the Hands-free audio device in Sound settings.
Go to Settings > System > Sound > More Sound Settings > Playback tab > Right-click the Hands-free audio device > Disable. Do the same on the Recording tab.

Answer 3

I agree with @Rodrigo Queiroz

(Go to Settings > System > Sound > More Sound Settings > Playback tab > Right-click the Hands-free audio device > Disable. Do the same on the Recording tab.)

Just want to add that in most cases, it stays disabled after reboot unless

• You remove and re-pair the earbuds
• Windows updates your Bluetooth drivers and re-enables them
• Or if you reset your FreeBuds

You can also manually force to use of Stereo Audio by following these steps:

-
Click the volume icon in the taskbar

• Click the arrow (>) to expand audio outputs
• Choose the one that ends in Stereo, not Hands-Free
• You’ll usually see Huawei FreeBuds Pro 4 Stereo and Huawei FreeBuds Pro 4 Hands-Free AG Audio.
  You can choose the Huawei FreeBuds Pro 4 Stereo and avoid the other one.
