    Description: High Definition Audio Controller

    Manufacturer: Microsoft

This showed sound card is causing the problem, but this one in fact is not the sound card(realtek in my case). The culprit is "Intel(R) Display Audio" in Device Manager - Sound video and game controllers.

As of 2023, update Intel graphic card drivers did not solve the issue. 

Disable this "Intel(R) Display Audio" would solve the problem. It is used by hdmi / direct Wifi to allow tv to play sound.
