The problem with this is that the Shokz headset is no longer recognised as a mic input, and only a headset device for listening.
The Windows machine defaults to its internal micrephone for voice input. So if you were to walk away from the laptop you cannot be heard.
This is what I get, unless you are getting something different to this
I experienced this as well. When I connected the Shokz after making the change of turning off the service, the mic stopped functioning on the Shokz, and Windows showed the device as Connected Music, and it usually shows Connected Music, Voice.
It does serve as a workaround if you have another mic you can use since you can specify a separate mic and speaker in Teams.
