No sound on startup with Realtek USB Audio until minimized

Minecraft Bedrock Edition does not produce sound on startup. Minimizing and reverting restores the sound.

I have the problem with Realtek USB Audio, but when I try to use other sound devices such as headphones, this symptom does not occur.

To reproduce this phenomenon, launch Minecraft with the Realtek USB Audio connected. Immediately after that, you can confirm that there is no sound.

To revive this phenomenon, minimize the game while it is running and return it to the game screen to restore the sound.
