Probably duplicate but I'm not seeing any solution that works.  Audio volume is fine on my laptop across multiple programs until joining with computer audio to a Zoom meeting, then volume drops.  I have the speaker volume at Max and have turned off, unchecked Automatically Adjust Microphone Volume, and set Audio Profile to Zoom Background Noise Removal to Low (although I have tried Auto, Medium and High but no change).  Why does Zoom automatically change the volume?  What else am I missing?  I don't seem to see any other fixes posted other than the uncheck auto adj mic volume and that doesn't fix it.  The laptop is 3 months old running Windows 11 Pro (although I had the same problem with the laptop this replaced)

I am struggling with my Zoom camera. When I join a meeting, it shows my screen as grey with a laptop on the screen. The camera on my laptop is circled. I am not sure how to fix this. This has never happened to me before.  I am not sure if my camera should be the same as the system or integrated system. I am also not sure what the video rendering method and hardware acceleration option should be. I looked at the troubleshooting steps and I am honestly lost as where to start to fix this. I wish I could attach a photo of my screen and settings. It is also disappointing that I cannot receive support from a live agent unless I have a paid subscription. 

when I try to share my computer audio when sharing my screen,

A prompt comes up and asks me to input my administrator username and password to download an audio device.

I am using a MacBook. Not sure which version of Zoom I have.

Is there a way around this? Why is my Zoom doing this?
