I need to disable Handsfree Telephony to make my Sony WH-1000XM4 headphones work in MS Teams (as resolved in this thread).
But, the setting keeps being enabled again - possibly during reboot or bluetooth re-connection.
Is there a way to PERMANENTLY disable the setting for this device?
Aside: I'm open to a fix in powershell if anyone knows the API calls for toggling the setting based on BT connection trigger.

Hi logularjason,
I'm Rodrigo and I'll help you.
If the Hands-free telephony option is reenabling after the restart, another option is to disable the hands-free device under Settings > System > Sound > More Sound Settings > Recording tab and under Playback tab.
Test it and tell if it changes after the restart or reconnection. if it doesn't work we can try other fixes.
Example:
Hi,
I haven't found a way to switch off hands free telephony permanently - no matter what I do, it always turns itself back on.
Disabling the microphone device in sound control panel does not prevent windows 11 switching to headset mode whenever an application uses a microphone.
The solution I found was to disable the hands free driver for the device:
Using the device property page found from "Control panel" -> "Hardware and sound" -> "Devices and printers" go to the hardware page and disable the hands free system device.
After this process, even though hands free telephony turns back on, it is unable to select the hands free device and the headphones stay in audio mode, rather than headset mode.
This has saved me from going back to Windows 10 for the second time. Thank you very much.
thank you very much, this solved the problem.
I tried using both meathods but eitherway as soon as i restart my pc the hands free telephony is back and enabled again, do you have any idea what could cause this?
