Why this is happenning?

[AmberSmith]

We are the 45 pupils' for the training of pressure cleaning services. All of our classes are available online because our students come from all over the world. Some students report that even though I normally act as the meeting's host, the voice eventually turns quiet. Some pupils deal with this, but not all do. The meeting must then be adjourned and reopened, which takes a lot of time.

I have no idea why this is happening at all. Please investigate this matter!

Hi, @AmberSmith.  Is this the same problem you reported back in September 2022?

Has this problem continued since then, or did it stop and now started again?

I don't really have enough information here to diagnose and troubleshoot for you.  Next time it happens, I recommend taking a moment and running the Test speaker & microphone check, and see if YOU can hear the recorded voice through the mic to your own headset.

What type of mic are you using?  Are you staying near the mic?  Is there other noise going on that could overpower your voice?
