Hello, PauliusRuplys,welcome to inquire about the Microsoft Community.
Thank you for your feedback. According to your description, you are experiencing an issue where a specific microphone automatically unmutes itself after an update.
This may be due to the fact that the microphone's mute status is implemented through the driver, and once the working application is changed, that status does not apply to the new application, resulting in the mute being lifted. To fix this issue, you need to report it to the microphone's manufacturer, and they will resolve it through a driver update.
In any case, Windows does not automatically decide whether a device is muted, so please understand.
In addition, you can also submit your questions through the FeedbackHub (if convenient, please provide as much detail as possible, including pictures, videos, etc.).
