I want to live stream a church service using Zoom to those unable to attend in person.

I have a MacBook Pro using MacOS Ventura 13.5.

I used to have no problem with my old MacBook before I bought my new one.  The last time I did it - using the new MacBook - those attending by Zoom could only hear the Minister who wore a microphone and could not hear the organ music nor the congregation singing the hymns. 
What settings do I need to use to ensure people attending via Zoom can hear the whole service, including the loud music and hymns, as well as those reading the readings and delivering the sermon? 
I usually start a Zoom service via the web on Safari. Is this the best way? 

I'm using Windows 10.
I have zoom on my laptop.
When I'm not connected to internet, my zoom application keeps giving me pop-ups that cover the foreground and never go to the background even when I click on other apps. Even when I want to do something without internet, I can't do anything because the pop-up covers the screen.
That pop-up says something like unable to make secure connection.
Even after I close that pop-up, it pops up again and again and again.
I want it to stop doing that. How can I make it stop?

Hi,
  I broadcast a Church Service via Zoom using a video camera plugged into a Windows 11 laptop (HDMI to USB).  All works sort of OK.  But a big problem is Original Sound.

The system used to remember to leave Original Sound in its previous (on) state.  But now it always defaults to the Original Sound=Off.  No problem, I hear you say, just switch it On every time.  I Do.  Until I don't.  Every once in a while I forget and the service is broadcast and recorded with unusable sound.  The spoken word is barely listenable and the singing is broken up and awful.  

Is there any way to force Original Sound=ON as the default please?

I have seen one comment elsewhere about a registry setting.  But the registry tree it talks about is not present on my machine.  So I'm guessing that must be windows 10.

Once I have that solved , I'll need to fix the very low resolution of the recording.  Nothing I do seems to address that.  As presenter, I always use HD mode for my image and can't control other people.

Thanks

I am using Samsung/Android and just today noticed I can't remove the blur from my Zoom background.  I have tested on different Zoom accounts and the "blur" is on all of them.    It is not quite as blurred as the "Blur" option in the "Background & Effects" but clearly out of focus even thoughts I tap "none" .

This seriously affects my work so would urgently need help.
Has anyone seen this behavior or know how to correct it?

I use Zoom for my yoga classes since many years without issues. Since about a month, I think since Zoom update to Workplace, I start my class sharing music from Spotify, as always, and using my Rode Wireless microphone. Suddenly, my mic disconnect and no more sounds are shared. When I try to unplug my mic or adjust the setting in Zoom, the whole app freezes and stop working. I have to start the meeting again and use my laptop microphone instead of my Rode microphone. Is there a solution to this issue??
