Problems persist in 5.11.1 with this device. In my case, if video is passed but audio is not (despite being present on the machine as verified in Blackmagic Media Express), the workaround on a MacBook Pro/Monterey 12.4 (and I expect Catalina 10.15.7 but not yet confirmed) is to switch the VIDEO source to Facetime, then back to Blackmagic UltraStudio Recorder 3G. That starts passing audio here. I've reported this to Zoom and have been advised that the issue is "already escalated to our engineering team for further investigation".
To speak to the OP's video issues, I had problems getting settings working for video transfer with a Canon XA45. I was unable to work out an output setting that worked for HDMI, but found something that worked for SDI. Not having the camera nearby, it had something to do with PsF (or not)--one of the output formats worked, the other did not. Sorry, I can't remember which!
My audio report to Zoom follows:

Hello, Zoom. We were using Zoom 5.11.0 last week for a live show and had lots of problems getting audio to work from the Blackmagic UltraStudio Recorder 3G running latest firmware. On macOS Monterey 12.4 and Catalina 10.15.7 both. Video was fine, but audio repeatedly did not work. Made top of show rather interesting! We were trying all sorts of settings toggles.
This is not fixed in 5.11.1. Video is passed, but no audio is present at Prefs, Audio, on the meter. The failure is, however, random. I've been able to reproduce it on Monterey 12.4 as described below. I have not re-tested Catalina 10.15.7.
Our camera is connected on SDI. HD is ON, Mirror is OFF, Touch Up is OFF. Hardware acceleration is ON, Optimize with denoise is OFF. High fidelity music mode is ON. Original Sound is ON.
If audio is not working with this device, toggling the video source to Facetime camera then back to Blackmagic restarts audio.
If we End meeting and quit Zoom with the Blackmagic device active, on restarting Zoom audio is broken again, though the Blackmagic device is apparently selected for both video and audio. Toggling the video source to Facetime camera then back to Blackmagic restarts audio.
Toggling audio source to MacBook Pro mic and back to Blackmagic breaks it again, after which toggling video source to Facetime and back again gets it working.
By not working, verify from meter in Prefs, Audio.
Note also here that you cannot set input level with the slider when auto-set is unchecked: it resets to 0 immediately every time you try to raise it from 0. Please fix this too.
There have been several failures with this device, fixed in 5.9.6 and again in 5.10.3 per release notes. Please verify that this device works reliably; it is a mission-critical tool. Please verify that it does not fail when toggling between devices, or when zoom is started with device connected.
Thank you,
