I'm on Windows 10, and the master volume control can't adjust the audio outputting from my PC to my phone. Is this a new feature or a bug?

Description

Currently, on video platforms like YouTube and Bilibili, adjusting the volume within the video player syncs to my phone without any issues. However, when I adjust the master volume using the slider in the bottom-right corner of Windows 10, the volume output to my phone does not change and fails to sync. I’m not sure if this is due to a virtual audio device issue or a bug, but if it can be adjusted, I would really appreciate it if this feature could be added. Thank you!
