Radio button causes sound problem

[Chrieg]

Hello F1 fans,
I got a really strange problem:
When I use the radio button to display the radio messages, it's causing my sound to be interrupted for approximately 1 second and then the sound is comes back really muffled.
When the radio message menue disappears and I tab out and back into the game (Alt+Tab) the sound is back to normal.
I mean, wtf?
Has someone else discovered the same problem?
I'm using bluetooth headphones and tried several settings (changing sound device setting to headphones, tv speakers etc., don't lower volume when engineer is speaking and whatever), but it doesn't help.

So I did some more testing and at least I can pinpoint the problem a little bit more:
So pressing the radio/voice control button enables the user to use voice commands to calling for pit stop, check the weather and so on. In this mode the sound get's muffled. But even when I'm done with the voice command and the menue closes, the sound never comes back as it was before. At this point I have to tab out and back in into the game to get the normal sound.
This does not happen with normal speakers and is only happening when using bluetooth speakers with an inbuilt mic.
My question is now, how to get back to the normal sound or maybe disable voice recognition completely to avoid this problem from the beginning?

I'm using Win 11 + Sony WH-1000XM5 by the way

I have exactly the same problem. No idea how to fix it though.

try disabling 'handsfree telephony' in Win11 :

Open Windows 11 Settings.
Select the Bluetooth & devices category from the left side.
Now, click Devices.
Scroll down and click on the More devices and printers settings. This will open the Devices and Printers page in the Control Panel.
Right-click on your Bluetooth device and select Properties.
Go to the Services tab.
Uncheck the Handsfree Telephony checkbox.
Click Apply and then click OK.

I don't know what this does in Windows and what will / won't work anymore, but it solved the game-issue
