MIC selecting issue on zoom meeting via MTR on windows

When joining a Zoom meeting from an MTR-Windows device, the room’s default microphone is not detected automatically, and the microphone must be manually selected each time. This issue occurs only in rooms with DSP audio.

I reviewed the articles, and they indicate that the default microphone and speaker must be selected in the Windows settings for rooms using DSP audio.

My question is whether this is expected behavior. As we had not observed this issue previously; it started occurring approximately two weeks ago.
