+1 for this.
More specifically, +1 for basic control of this at a host level so they level out the imbalance in audio for everyone.
A super simple volume mixer with individual volume and overall compression can’t be that difficult to throw into the mix.
You are always going to have people who do not know how to fully use Zoom yet need to speak in the meeting and end up being too loud or quiet while everyone else is on the receiving end of it all.
When this is extreme, often the only solution is for each participant to manually turn the volume up or down on their own speakers. The host in the meantime gets complaints about people being too quiet or too loud while not being able to do anything about it. Not a great user experience when you have to focus on managing that rather than the content of the meeting itself.
What’s often overlooked is the fact that you cannot really hear yourself in relationship to everyone else on line. You basically need to rely on everyone else to tell you if you are too loud or quiet, or hoping for Zoom auto to kick in correctly. This is fine one on one, but not with a group of people where everyone has their own set of volume knobs on their own computer system.
Some simple AV controls are crucial.
